No! it is not a duplicate of the bug of /usr/share/kde4/services/ScreenSavers directory my directory is already chmod a+rx but the problem persists The systemsettings (and kcmshell4 screensaver) chrash also if I create a new empty /usr/share/kde4/services/ScreenSavers with chmod a+rx, but works well if I delete/reneame the directory (systemsettings show an empty list of screensavers)
ops.... wrong status
If I try to show a screensavers list after the command chmod 744 /usr/share/kde4/services/ScreenSavers I see an empty List and systemsettings works well On another machine with debian (same version) there aren't crash , but the list contains duplicates of some screensavers I think something.... KDE create and save to disk a files who contains a list of screensavers anytime I invoke the systemsettings ? If yes, where is this files? maybe to be not writable
Francesco, it is the same bug, it crashes inside Qt when calling XVisualIDFromVisual() while creating a widget. Workarounds may work for one, but not for the other. The bug depends on X11 and graphics drivers and version also. It may also be a Qt bug. *** This bug has been marked as a duplicate of bug 188623 ***
