Bug 269143

Application: ktorrent (3.3.4)
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-30-generic i686
Distribution: Ubuntu 10.04.2 LTS

-- Information about the crash:
When viewing chunks and changing the sortation it caused the crash.  I repeated the same actions three times to be sure that the crash was not just random and that it had to do with my viewing the chunks and changing the sortation.  I have not had this problem with other torrents so just in case it might be helpfull I was downloading archlinux-2010.05-core-i686.iso.torrent

I am running ktorrent from Gnome desktop however I also have KDE 4 installed from the Ubuntu/Debian repository.

The crash can be reproduced every time.

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