Description drdrnewman 2011-01-26 23:06:08 UTC 
Application: ktorrent (4.0.3)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-24-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
Every time I close down Ktorrent, with a File/Exit, it crashes instead of closing down.

It makes no different whether I have enabled microtorrent or not.

I am running Kubuntu 10.10 on a 64-bit platform.

The crash can be reproduced every time.

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