-- Information about the crash:
I had a cat window with multiple tabs and contacts open. Now I want to chat with a other contact and open kopete main window. then I dragged the contact to the chat window (i hope that kopete will open a new tab in the existing chat window) and copete crashed.

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