Bug 268219

Application: ktorrent (4.0.3)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-27-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
well... Sleeping - I had left my downloads going while I was asleep

- Custom settings of the application:
I have the program set to alocate all disk space from downloads to prevent this type of error. From reading other reports I have found that uTp protocol can be a problem and I have that enabled as well.

The crash can be reproduced every time.

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