Application: kmail (1.13.5)
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.6.3
Operating System: Linux 2.6.32-5-amd64 x86_64
Distribution: Debian GNU/Linux testing (squeeze)

-- Information about the crash:
I was hand deleting several messages at the same time from the Trash (that is, not moving them TO the trash, but deleting them FROM the trash) by CTRL-clicking a bunch at a time and hitting DEL key. Kmail crashed exactly one of the times. I wrote some letters in the search bar, hit CTRL-A to select all messages in Trash having that letter combination, and KMail crashed in the moment I hit DEL key.

 -- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
The current source language is "auto; currently asm".
