icedove segfaults several time a day for me. I have often suffered data loss by daring to try to do something else while icedove waits for a slow SMTP server. On segfault, the outgoing message is lost (unless manually saved as a draft). This bug should be RC.

The segfault is quite easy to reproduce: with the message pane open, and focus on the folder message list, use the up or down arrow keys to quickly scroll through messages.

This attached log is created with the icedove 1:45.2.0-2+b1 amd64 from the unstable repo and the official debug command line:

LANG= /usr/lib/icedove/run-mozilla.sh -g /usr/lib/icedove/icedove-bin --safe-mode 2>&1 | tee ~/tmp/icedove-gdb-$(dpkg-query -s icedove | grep Version | cut -f3 -d":")_$(date +%F_%T).log

segfault:

Thread 1 "icedove-bin" received signal SIGSEGV, Segmentation fault.
