Application: kopete (1.3.4)
KDE Platform Version: 4.9.4
Qt Version: 4.8.3
Operating System: Linux 3.5.0-18-generic x86_64
Distribution: Ubuntu 12.10

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

Get a link from Jabber in kopete
Drag link out of the window
If does not matter where you drag the link to
As soon as the cursor left kopete's window, it crashes

Perhabs it is notable that I have focus under mouse, if cursor enters another window, kopete looses focus.

This happens since years, I always use the latest Ubuntu.

The crash can be reproduced every time.

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