Arch Linux

Description:
Impossible to change settings that needed the root privilegies in KDE systemsettings. Clicking the Apply button nothing happens but clicking the back or close button a dialog box appears prompting for apply the changes. Clicking the new Apply button a new dialog box shows the message: 'Unable to authenticate/execute the action: (code 3)'
Running KDE systemsettings from 'kdesu systemsettings' or 'kdesu kcmshell4 kdm' the same error occurs.

Additional info: Kdesu works no problem. Dbus is started from rc.conf before kdm. Arch clean install on june 27.
* package version(s) KDE 4.8.4
* config and/or log files etc.
