Comment 28 for bug 366398

The workaround shouldn't be necessary if you have DBUS with autolaunch support (it was added to dbus at some point, no idea in which version).

"kdesu dolphin" works fine here, and for Andras Mantia.
We both see a dbus-daemon running as root (with --autolaunch).

If dbus autolaunch doesn't work for you, I have to blame either a too old DBUS version, or a distribution with a bad dbus setup possibly.
