I had tried to ungroup through settings before: http://forum.kde.org/viewtopic.php?f=83&t=98489 albeit KDE4 still groups similar tasks. So I decided to right click on leafpad > More Action > Do not allow this program to be grouped. - Unusual behavior I noticed: plasma-desktop crashed, kicker panel (I think that's what it was called) disappeared and I immediately lost my personalised background (background went to solid black). My other programs such as Dolphin and Gkrellm were still running (visible) but I cannot see other programs that was on the kicker panel. Although after Crash Reporting Assistant loaded up I got plasma-desktop reloaded. I have tried grouping leafpad programs together but plasma-desktop crashed (again). After plasma-desktop came back, I tried ungrouping leafpad programs and same thing (plasma-desktop crashed). I'd say the occurance of this bug to appear would be always. - Custom settings of the application: None that I am aware of. leafpad is not part of KDE suite but it has become my GUI text editor of choice. I only had two instances which made KDE group them (along with other tasks that I did not want grouping to occur in any of them). The crash can be reproduced every time. -- Backtrace: Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault Using host libthread_db library "/usr/lib/libthread_db.so.1".
