Bug 245158

Application: ktorrent (4.0.2)
KDE Platform Version: 4.4.93 (KDE 4.4.93 (KDE 4.5 >= 20100713))
Qt Version: 4.7.0
Operating System: Linux 2.6.34-12-default x86_64
Distribution: "openSUSE 11.3 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
Like the title suggests, I was removing a finished download (Arch Linux Net-Install ISO file). KTorrent managed to remove the file from the download list but crashed immediately afterwards...

-- Backtrace:
Application: KTorrent (ktorrent), signal: Aborted
