Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

I have been getting a lot of crashes when I run 'emacs --daemon' and
then connect to it using 'emacsclient -c' with multiple $DISPLAY
values. The crashes usually happen when or shortly after I close a
window started on a different $DISPLAY than the one I started --daemon
in.

I'm sorry I can't be more specific -- the bug happens pretty frequently,
but I haven't been able to produce a completely reliable reproducer. I
managed to catch the crash in gdb, thuogh, so I figured I'd submit the
bug with the backtrace (which looks like it might be informative).
