Application: kontact (4.10.1)
KDE Platform Version: 4.10.1
Qt Version: 4.8.3
Operating System: Linux 3.5.0-26-generic x86_64
Distribution: Ubuntu 12.10

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

After login Kontact is started twice when loading last desktop session. This leads to problems and Kontact crashes after some time.

The crash can be reproduced every time.

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