Package: emacs
Version: 23.2+1-4
Severity: important
emacs infrequently crashes for me. Unfortunately I'm not able to get a
meaningful backtrace, despite at least trying to follow
http://wiki.debian.org/HowToGetABacktrace
Since the crashes happen only about once every 2 days, and I have no
idea under which circumstances they occur, I'm a bit reluctant to run
emacs in gdb all the time.
I installed the debugging packages I *could* find, however there seem
to be quite a lot of symbols missing.
However I already did
DEB_BUILD_OPTIONS="nostrip noopt" fakeroot apt-get -b source emacs
and installed the resulting packages, so the next backtrace hopefully
should contain more interesting information.

Unfortunately frames #13 to #42 contain nothing. There's a little
snippet from startup, which is probably inconsequential:

I've seen gtk-emacs crashing with emacs from cvs back in 2009 (in
october), but my solution back then was to simply disable gtk. Since
emacs 23 with multi-tty support has become available in debian, I've
switched to the debian packages, which went fine, until gtk support
was switched on by default.
I'll be thankful if somebody could advise how I can provide the
missing pieces of information.
