Bug 324938

Application: ktorrent (4.3.1)
KDE Platform Version: 4.11.1
Qt Version: 4.8.4
Operating System: Linux 3.11.0-7-generic x86_64
Distribution: Ubuntu Saucy Salamander (development branch)

-- Information about the crash:
- What I was doing when the application crashed:

i did other things with my computer.
KTorrent sat minimized in the task tray.
This now happened several times, after 4-8 hours of runtime.
KTorrent crashes with a stacktrace similar to the former report.

The crash can be reproduced every time.

-- Backtrace:
Application: KTorrent (ktorrent), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
