KDE Platform Version: 4.10.2
Qt Version: 4.8.4
Operating System: Linux 3.8.0-19-generic i686
Distribution: Ubuntu 13.04

-- Information about the crash:
- What I was doing when the application crashed: it crashes at startup.  After Kubuntu 13.04 upgrage Kontact (kdepim) won't start.

The crash can be reproduced every time.

-- Backtrace:
Application: Kontact (kontact), signal: Illegal instruction
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".
