Bug 218528

Application that crashed: ktorrent
Version of the application: 3.2.4
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-16-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
Sometimes it will immediate happen when you open and other times it will take a week to crash.  This time it crashed it was in the middle of the night with only 2 torrents going.

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