The backtrace looks like a Qt/Painting crash. However libmsn beta8 is causing really weird crashes all over the place; this could be related to it.
- Does Kopete crash again if you repeat the situation you described ? if it does, can you check that downgrading to libmsn beta6 fixes the crash ?
Thanks

Waiting for feedback. Marking as NEEDSINFO.

This indeed seems to be a Qt painting bug. We received a report about Dolphin crashing in the same painting code at Launchpad: https://launchpad.net/bugs/465433
