-- Information about the crash:
I was listening to music and Ktorrent was uploading one torrent. Then everything froze except the mouse. I then tried to click on a Firefox Window from the taskbar and it showed up blank. Then Ktorrent closed and showed the crashed dialog.

The crash can be reproduced every time.

 -- Backtrace:
