Application: kontact (4.10.4)
KDE Platform Version: 4.10.4
Qt Version: 4.8.4
Operating System: Linux 3.8.0-26-generic x86_64
Distribution: Ubuntu 13.04

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

I had just apdated my system via muon.
Maybe the update package involved is qt4 

Even is I rebooted, kontact crasces everytime I try to start it up.

The crash can be reproduced every time.

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