Bug 272548

Application: kopete (1.0.80)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-29-generic i686
Distribution: Ubuntu 10.10

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

I used drag'n'drop for URL as usual except for path of dragging. Usually it is horizontal: from jabber conference chat window on the right display to firefox window on the left. Sometimes through pager on bottom panel, because kopete is sticked on all virtual desktops, but browser is not.

Now I started to drag over top side through tabs, panels and window decoration and it crashes.

Not shore if it is raleted with some of the bugs that was displayed by DrKonki.

The crash can be reproduced every time.

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