Application that crashed: kopete
Version of the application: 0.70.90
KDE Version: 4.3.1 (KDE 4.3.1)
Qt Version: 4.5.2
Operating System: Linux 2.6.28-15-generic x86_64
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
Came home from work and saw that Kopete had crashed. Tried to restart it, but the application does not even have time to draw a window before crashing again.

I have the following account types:
ICQ, Jabber, Skype, Live Messenger, Avahi

Starting from Konsole gives the following output:
