<Resend because of missing subject in previous attempt> I realize this bugreport seems a bit strange, even to me, but as it was 100% reproducible so I decided to try a gdb backtrace. The crash only occurs on these 6 characters as far as I can tell, variations don't seem to trigger it. The first backtrace pasted below is the one that I normally get, when trying to send the mail after it has downloaded all incoming mail, etc.
After the crash, I tried a second time from a clean state, after restarting X, and this time I succeeded to send the email once, but a second try failed with a different backtrace, pasted below the first. Seems to be memory related ? It's a real mystery to me what the cause could be. ---first backtrace--- /usr/lib/icedove/run-mozilla.sh -g -d gdb icedove-bin MOZILLA_FIVE_HOME=/usr/lib/icedove LD_LIBRARY_PATH=/usr/lib/icedove:/usr/lib/icedove/plugins:/usr/lib/icedove DISPLAY=:0.0 DYLD_LIBRARY_PATH=/usr/lib/icedove:/usr/lib/icedove LIBRARY_PATH=/usr/lib/icedove:/usr/lib/icedove/components:/usr/lib/icedove SHLIB_PATH=/usr/lib/icedove:/usr/lib/icedove LIBPATH=/usr/lib/icedove:/usr/lib/icedove ADDON_PATH=/usr/lib/icedove MOZ_PROGRAM=icedove-bin MOZ_TOOLKIT= moz_debug=1 moz_debugger=gdb /usr/bin/gdb icedove-bin -x /tmp/mozargs.kKOzH9 GNU gdb (GDB) 7.2-debian Copyright (C) 2010 Free Software Foundation, Inc.
