Bug 291606

Application: ktorrent (4.1.1)
KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-14-generic i686
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:I started a big torrent (approx 20g) that was paused earlier. Crashes even with minimum apps running (with max free memory)

- Custom settings of the application:graph plugin on, maybe something else, minor.

The crash can be reproduced every time.

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