Sentry Crash Report:

Description Leandro Santiago da Silva 2010-11-13 18:12:45 UTC 
Application: ktorrent (4.0.3)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-22-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
Ktorrent crashed after stop all downloads and start a new one.
I've selected all seeding, waiting and downloading downloads with ctrl+a and choiced "stop all". After this I selected the only one incomplete download and choiced "start". So KTorrent crashed.

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