Application: kontact (4.11.1)
KDE Platform Version: 4.11.1
Qt Version: 4.8.5
Operating System: Linux 3.7.10-1.16-desktop x86_64
Distribution: "openSUSE 12.3 (x86_64)"

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

I clicked shutdown in the menu that pops up after hitting the shutdown button in the shutdown widget. Every once in a while Kontact crashes while KDE is being shut down.

I can't open any other windows so I can't look for the bug report about Kontact crashing at shutdown that was recently closed with NEEDSINFO - will add it later (although it might be a different bug here since Konqi did not find any possible duplicates from the backtrace)

The crash can be reproduced sometimes.

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