Sentry Crash Report:

Description Santiago 2012-07-11 02:33:23 UTC 
I was working with the Dolphin as usual, and suddenly the ktorrent closed unexpectedly.
I had the window open Ktorrent, but I had it in the background on the system tray.
This is the first time since I updated KDE 4.8.4 this happens to me.

Reproducible: Couldn't Reproduce
