Bug 305563

Application: kopete (1.2.3)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.2
Operating System: Linux 3.2.0-3-686-pae i686
Distribution: Debian GNU/Linux unstable (sid)

-- Information about the crash:
- What I was doing when the application crashed:

I was pulling a Firefox tab out to be in it's own window; to do this I had to pass by Kopete, which then crashed.

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