Kubuntu 11.10 Ktorrent 4.2 Linux (x86_64) release 3.3.0-030300rc5-generic I upgrade from KDE 4.8 to 4.8.1 via PPA After upgrade ktorrent freeze if: 1) I watch a video long about 1 hour 2) system go in power saving for about 1 hour. No information on log file. 1. Start ktorrent 2. wait about 1 our in power state mode 3. ktorrent freeze, the window became white. Right click mouse on system try icon open the menu but no operation work.
Looks like a deadlock. When it happens do this in a terminal: killall -11 ktorrent This will trigger a KDE crash dialog, use it to generate a backtrace and post that here.
