Version: 3.0 (using KDE 4.1.3) OS: Linux Installed from: Unspecified Linux The KDE logout is real chaotic: Plasma exits, then there are windows with the tray icons. Then the other applications exit and everything is black. Suddenly you see KDM or the splash screen. There could be something like the start screen.
somewhat different purpose, but same solution. the other report is more verbose, so marking this one as the dupe. *** This bug has been marked as a duplicate of bug 188476 ***
