Bug 270733

Application: ktorrent (4.0.3)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.0
Operating System: Linux 2.6.38.2-ck2 x86_64
Distribution: Ubuntu 10.10

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

While investigating bug https://bugs.kde.org/show_bug.cgi?id=270272 I tried installing the logviewer. Upon completion of downloading a torrent, I closed the integrity checker, then removed the torrent from the list. The logviewer spewed all sorts of warnings about invalid token or something and then crashed.

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