KDE Platform Version: 4.8.00 (4.8.0 "release 2"
Qt Version: 4.8.0
Operating System: Linux 3.1.9-1.4-desktop x86_64
Distribution: "openSUSE 12.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed: I would like to change the status of message, so I click on junk icon for one message, Change to another one click on, click off.
Return to the first one, and click to set status off.
The crash occurs at that time

The crash can be reproduced some of the time.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
