Sounds plausible...

Can you get a backtrace from a crash by running gschem under gdb?

If possible, get a few and see if it crashes in the same place each
time.

Did you compile gschem yourself? The stack traces are of course only
useful if gschem was compiled with symbols intact (unstripped), so we'll
have to see!
