This bug is likely due to the changes in Dbus security associated with
CVE-2009-0578. Another discussion of it can be found at
https://bugzilla.novell.com/show_bug.cgi?id=486267.

Some systems are fixed by deleting an extraneous directory
/var/run/dbus/at_console/root. Others need changing of the "at_console" rules.
If you do not have the extra directory or deleting it doesn't help, try the
patches for /etc/dbus-1/system.d/nm-applet.conf or
/etc/dbus-1/system.d/knetmamager.conf.
