Application: kontact (4.7.0)
KDE Platform Version: 4.7.00 (4.7.0)
Qt Version: 4.7.3
Operating System: Linux 3.0.0-2-desktop x86_64
Distribution: "openSUSE 12.1 Milestone 3 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed: After opening kontact in overview mode, the mail panel didn't show new mail on monitored folders. I clic on mail icon and get the crash. 

I've found the duplicate, but we don't have qt 4.7.4 yet.

The crash can be reproduced every time.

-- Backtrace:
