First of all, let me mention that one crash per hour is pretty much ok for Synfig. So I don't see much reasons to treat your case as "more unstable than usual". ^__^
Analysis of core file sent by you doesn't gives me anything valuable. Without any additional information (i.e. steps to reproduce the problem) I cannot help you. Please try to track your activity and find the pattern triggering the crash, then report it to the bugtracker.
There is only one thing I can advice in such conditions: try to close the Navigator Panel - it might heavily increase the program stability. ^__^
