Application: ktorrent (4.0.3)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-22-generic-pae i686

-- Information about the crash:
- What I was doing when the application crashed:
Crash happens everytime I exit Ktorrent and will also occur during normal operation, backtrace is from a crash upon exit. 

I also have constant crashes when leaving Ktorrent running overnight and check in the morning to find it frozen. 

Backtrace is from a crash upon exit further backtraces can be provided if needed.

The crash can be reproduced every time.

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