Bug 216252

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 2.6.31-14-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
I honestly do not know why ktorrent crashes. Impossible to know trigger, random time, enough harddrive space.

 -- Backtrace:
