Application: kontact (4.10.1)
KDE Platform Version: 4.10.1
Qt Version: 4.8.3
Operating System: Linux 3.5.0-25-generic x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
- What I was doing when the application crashed:
I generally leave Kontact running all the time, and just close it to the system tray. Most of the time, when I try to open it when it's already running, via any method other than clicking its tray icon, it crashes.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Kontact (kontact), signal: Aborted
