Comment 1 Oleg Atamanenko 2011-10-24 08:37:50 UTC 
Created attachment 64826 [details]
New crash information added by DrKonqi

plasma-desktop (0.4) on KDE Platform 4.7.1 (4.7.1) using Qt 4.7.4

- Unusual behavior I noticed:
Crash after I changed settings of the task manager widget.
Also I found that settings of max row count is not respected.
