[SOLVED] Synfigstudio 0.61.09 crashes with LC_ALL=fr@euro

jerome · **Posted:** Tue Jan 06, 2009 6:34 pm

Hello to all,

I would like to report

A segmentation fault of synfigstudio 0.61.09:
- at splash screen, during "History initialization" (or some name like that)
- the text messages relate the event to "Invalid UTF-8 string passed to pango_layout_set_text()" and the crashes occurs in g_markup_escape_text() from glib.
a workaround for my box: $ LC_ALL=C synfigstudio
(my locale, with which synfigstudio crashes, is "fr_FR@euro")
some details about how it compiles (or not) and crashes (or not)

I don't know if it is really a bug of synfigstudio or some misconfiguration of my linux box, but anyway some warning should be added to the documentation so new users are not surprised by a crash which they don't understand, specially if they launch synfigstudio from a graphical menu and hence don't see the messages on the command-line, and that (maybe) main synfig developers never faced if they configured their machine to work in English.

Best regards,

Jérôme

General information and internet lookup
I installed synfigstudio on a AMD64 Gentoo linux box (using sunrise overlay, 0.61.08 and 0.61.09 versions), along with synfig 0.61.09 and ETL 0.04.12. I got a segmentation fault after splash screen. It has already been reported at different places on the internet. See

http://www.mail-archive.com/debian-bugs-dist@lists.debian.org/msg511830.html (a similar crash)
http://dooglus.rincevent.net/synfig/logs/2008/%23synfig-2008-01-03.log (no crash but interesting discussion on the topic of non-en_US locales and execution warnings)

One similar bug had been reported to exist in the 0.61.08 version, corrected recently in the 0.61.09 release. This is obviously a different bug since it still exists in 0.61.09. The existence of two separate bugs has been reported at:

http://bugs.launchpad.net/ubuntu/+source/synfigstudio/+bug/292750

Debug information

Although I would like to provide backtraces, I could not compile synfigstudio with -ggdb option, because it would fail like this:

Code:

./configure --prefix=/usr --host=x86_64-pc-linux-gnu --mandir=/usr/share/man --infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc --localstatedir=/var/lib --without-libfmod --libdir=/usr/lib64 --build=x86_64-pc-linux-gnu --enable-debug

make[3]: leaving folder « /mnt/stockage/sys/tmp/portage/media-gfx/synfigstudio-0.61.09/work/synfigstudio-0.61.09/src/gtkmm »

(Some of the compiler messages were manually translated to English for ease of reading.)

Of course I would be glad if someone could help me passing the correct options to ./configure or to the CFLAGS.

Synfigstudio specifically crashes using this locale (at least):

Code:

$ echo $LC_ALL
fr_FR@euro

Filesystem is in ISO-8859-1, which usually causes me some problems to programs using GTK+. For example, Inkscape would not be able to open a file when the path contains non Latin-0 characters. But until now, it does not causes a crash to the software I use, and anyway synfigstudio crashes while it is called from a directory tree using only 7-bits ASCII characters.

To enable debug symbols and disable optimisation, do this:

./configure --enable-debug --enable-optimization=0

Once you've done that do 'bt full' in GDB after the crash.

Hello pabs, thank you for your reply, here is the backtrace, obtained with the configure options you suggested. (I tried to attach the file to avoid flooding the topic page, but the software told me txt file are not allowed.)

Set the plain text extension category to allowed, sorry about that.

What happens with LANG=fr_FR.UTF-8?

Can you get a backtrace with glib/gtk debug symbols?

jerome · **Posted:** Thu Jan 08, 2009 1:02 pm

LANG=... does not change anything, however LC_ALL does the trick. But you'll notice that there's a coding problem in the console, because my system is actually ISO8859-1 (or 8859-15 when supported), not utf8.

13:38:51 jerome jerome/ LC_ALL=fr_FR.UTF8 /usr/bin/synfigstudio

Synfig Studio -- dÃ©marrage de l'application ...

(it works fine)

(synfigstudio:25618): Gtk-WARNING **: Invalid input string
Segmentation fault

So I compiled Glib 2.16.5 and gtk+ 2.12.11 with debug symbols. The crash apparently occurs during the creation of toolbar-history, as there are some out of bounds addresses related to the "redo" action.

Regards,

Jérôme

(I did not find in the in the User Control Panel how to activate the "plain text extension category" and google was not very helpful--these are the first messages I ever posted on a phpBB forum, so I know nothing about this interface.)

No idea about the crash, but I would guess it is a bug in GTK+.

I suggest switching to a UTF-8 locale if you can or using LC_ALL for now.

I've ask about it on the GTK+ IRC channel, will post updates.

About the text thing, just name the crash dump foo.txt and attach it to your post.

I got an answer from the GTK+ IRC channel:

Code:

<pabs> Hi all. Can any developers help with this crash within GTK+ triggered by synfigstudio? it's a SIGSEGV in append_escaped_text when using LC_ALL=fr_FR.ISO8859-1 http://synfig.org/forums/viewtopic.php?p=2029#p2029
<someone> pabs: where is the problematic tooltip text coming from ? it is probably not valid utf-8
<pabs> isutf8 says the .po file is fine
<pabs> http://synfig.svn.sourceforge.net/viewvc/synfig/synfig-studio/trunk/po/fr.po?view=markup
<someone> are you calling bindtextdomain_codeset ?
<someone> make that bind_textdomain_codeset()
<pabs> seems not
<someone> see http://library.gnome.org/devel/gtk/stable/gtk-question-index.html#id3058702
<pabs> hmm, ok. thanks for the info

I don't really have time right now to make a patch, test and commit it; if someone else could, that would be great.

KiBi has proposed this patch, could you please test it?

http://alioth.debian.org/~kibi/tmp/main.cpp.diff

Apply with this:

Code:

cd synfigstudio-0.61.09
wget -O - http://alioth.debian.org/~kibi/tmp/main.cpp.diff | patch -p1

This patch works fine, thank you very much for your support.

Jérôme

pabs · **Joined:** Fri Nov 30, 2007 8:25 pm **Posts:** 292

Cool, I'll apply the patch along with a couple of others KiBi proposed to silence some warnings.

jerome · **Posted:** Tue Jan 13, 2009 8:52 am

So it does not crash anymore, but I found another weird issue. Now a few properties are not displayed with the proper coding. Window titles, general GTK GUI are OK, but the translation of the parameter names (Integer, Real, Z Depth, Amount...) is wrong when it has a non-latin-0 letter.

When launched with LC_ALL=fr_FR.UTF8, this problem does not show up (coding appears ok), it happens only now that it does not crash any more with ISO8859-1.

Below an illustration in the Params and History windows, for the parameter "Amount" ("Quantité").

Sorry for not seeing this sooner.

Best regards,

Jérôme

Could you please try the latest SVN versions? I committed another patch from KiBi that may also fix this.

jerome · **Posted:** Wed Jan 14, 2009 6:55 pm

I have a little proble in compiling from R2329 (canvasinterface.cpp:593: error: 'class synfig::Canvas' has no member named 'register_external_canvas'). I'll read the FAQ, try harder, and tell you more when I manage.

Jérôme

jerome · **Posted:** Fri Jan 16, 2009 5:30 pm

I took time to read and follow the build instructions and I can confirm that r2329 corrects both problems reported in this topic (crash and traduction coding).

Thank you again for your efficiency.
