Bug 249430

Application: kontact (4.4.5)
KDE Platform Version: 4.5.00 (KDE 4.5.0)
Qt Version: 4.7.0
Operating System: Linux 2.6.32-24-generic i686
Distribution: Ubuntu 10.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Kontact did no longer start from the kickoff menu, so I tried starting kmail from the command line. Then kontact just crashed with the attached backtrace.

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