Application: kmail (1.13.5)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-28-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:

Manually filtering messages with Ctrl-J. Also often crashes when doing automatic filtering. And often the messages dan't get filterd at all automatically (hence the need to do Ctrl-J). I've had this bug for about 2 weeks. Kmail crashes a couple times per hour.

The crash can be reproduced every time.

-- Backtrace:
