Bug 246679

Application that crashed: ktorrent
Version of the application: 3.2.4
KDE Version: 4.3.5 (KDE 4.3.5)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-18-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
error message says segmentation error
A couple of weeks ago, ktorrent became unstable, with many crashes.
This is totally new. For a long time ktorrrent has been rock solid stable.

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