Bug 256621

Application: kontact (4.4.6)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-22-generic x86_64
Distribution: Ubuntu 10.10

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

Just starting Kontact from KDE desktop. Nothing fancy. 

I experienced a power glitch and I had to restart my system. On restart Kontact was not working anymore. I might have done some package update before the power glitch.

my upgrade history is as follow:
