Application that crashed: kontact
Version of the application: 4.3.0 pre
KDE Version: 4.2.90 (KDE 4.2.90 (KDE 4.3 Beta2))
Qt Version: 4.5.1
Operating System: Linux 2.6.30-8-generic x86_64
Distribution: Ubuntu karmic (development branch)

What I was doing when the application crashed:
I wasn't doing anything in particular as I'm playing around a little with karmic alpha 2.
So no mail accounts configured, no contacts, no appointmens and the default feeds for akregator part.

The only "strange" thing i did was go to system settings, advanced and set up the akonadi resources. The migrations were successfull and thats it.
