Application: plasma-desktop (4.11.2) KDE Platform Version: 4.11.2 Qt Version: 4.8.5 Operating System: Linux 3.7.10-1.16-desktop i686 Distribution: "openSUSE 12.3 (i586)" -- Information about the crash: As there is NO group / ungroup this application in the context menu of an app in task manager, I right-clicked app icon in Task Manager > chose 'More Actions' > 'Don't Allow This App to Group' (what a pain). Crash. This happens Every Time. Please PUT Group / Ungroup BACK in the main body of context menu! The way it is now, in 4.11 is NOT an improvement, functionally or cosmetically. The crash can be reproduced every time. -- Backtrace: Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault Using host libthread_db library "/lib/libthread_db.so.1".
