-- Information about the crash:
- What I was doing when the application crashed:
I clicked on a torrent file attempting to open it just after upgrading to Kubuntu 12.04 beta 1 from Kubuntu 11.10.  Ktorrent worked fine in Kubuntu 11.10.  I haven't tried it again yet.

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