I see in the output from the crash:

> Fatal error 11: Segmentation fault

In the etc/PROBLEMS file, we have the following item regarding a crash
with the same error message:

> *** Emacs built with GTK+ toolkit can unexpectedly widen frames

Perhaps this should therefore be merged with the bugs mentioned there:
