I have a largish gtk2 application which uses g_thread and does a lot
of painting in idle handlers and I've not seen this problem. It sounds
like a horrible race condition :-(

I've found problems like this in the past by making the smallest
example I can that shows the problem, then using valgrind (or efence
perhaps) and lots of printf()s. A good log file can often reveal
timing issues.

Perhaps you could update every 10ms and get a crash sooner? Sorry not
to be more helpful.
