Can you provide an "xbacktrace" and "bt full" backtrace.

Please use M-x report-emacs-bug to include proper information
about your emacs version and environment, including additional
information about the crash (as instructed).

In any case, VM is one specific package which seems to be able to
crash emacs "quite consistently", but so far none of the VM users
have been able to help us really pinpoint what causes the trap.

If you can help in any way, it would be great.


Thanks.
