Bug 288154

Application: kontact (4.7.3)
KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.7.4
Operating System: Linux 3.1.0-2-desktop x86_64
Distribution: "openSUSE 12.2 Milestone 0 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed: I've upgrade ~600 packages with kde open. At the end I've ask to reboot the computers.
The crash was immediate, (note that kopete also crash at that time )

The crash can be reproduced some of the time.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
