Application: plasma-desktop (0.3) KDE Platform Version: 4.4.1 (KDE 4.4.1) "release 225" Qt Version: 4.6.2 Operating System: Linux 2.6.31.12-0.1-desktop i686 Distribution: "openSUSE 11.2 (i586)" -- Information about the crash: I expanded a group of about 8 windows, and had now some very narrow buttons in the task manager. While clicking one of them (RMB) and selecting "collapse parent group", it crashed.
