A segmentation violation in the server.

I would suggest you first try version 3.1.2E and see if the problem
can be duplicated.

If the problem still occurs, with 3.1.2E, you should try adding
"NoTrapSignals" to the ServerFlags section of your XF86Config file
and then get a backtrace from the core. Note that doing this is likely
to leave your video console in an unusable state when the segv occurs.
Just press CTRL-ALT-DELETE to reboot and then examine the core file.

As this is not an Fvwm problem, further discussion should be moved
somewhere more appropriate, such as comp.os.linux.x (and you should
send a copy of the backtrace to XFree86_at_XFree86.org).
