Application that crashed: kopete
Version of the application: 0.80.2
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.3
Operating System: Linux 2.6.29-2-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)

What I was doing when the application crashed:
My Kopete crashes when I close the messages history window.

This behaviour is stable; it crashes always and no matter where I have opened the window from (the context menu in the contact list or the main menu in the conversation window).

 -- Backtrace:
Application: Kopete (kopete), signal: Segmentation fault
