Application: ktorrent (4.0.3)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.38-020638-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
Nothing Just I have put King's Speech for downloading and it says after sometime that segmentation fault error.
It's after my OS (UBUNTU 10.10 with GNOME) hanged. It hangs randomely so I just reset PC with power button and now segmentation fault in Ktorrent what to do?

The crash can be reproduced every time.

-- Backtrace:
Application: KTorrent (ktorrent), signal: Segmentation fault
