description:
  Ice segfaulted when an xemacs window was being
closed, or something. I honestly can't remember exactly
what i was doing at the time that the session crashed,
but i know it had something to do with an xemacs
window. [this xemacs was compiled with gtk widgets; i'm
not sure if that has any bearing on the bug]


 this segfault has happened repeatedly.


backtrace:

Program received signal SIGSEGV, Segmentation fault.

this happened again, when i was switching virtual desktops,
using the mouse, at the right edge of the screen; the
segfault happened in the same spot in the code, but i didn't
save the backtrace from it.

and it happened yet another time, when i closed an xemacs
'gnuclient' window. this is the backtrace from that crash;
it's essentially the same as the first backtrace in this
bug-report.

Program received signal SIGSEGV, Segmentation fault.

apparently, other people aren't having this problem, but
it's been a major interruption on my desktop.

it'll be nice when this particular crash stops happening,
but ice is still a great wm.
