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 2.6.31-10-generic i686
Distribution: Ubuntu karmic (development branch)

What I was doing when the application crashed:
When someone invites me to a jabber group chat, kopete crashes.
Those trying to invite me, use iChat, if that is of any importance. Most of the times I don't get the notification, but once in a while kopete pops up a invitation dialog. When I confirm the invitation, the crash occurs.

 -- Backtrace:
Application: Kopete (kopete), signal: Aborted
