[Bug 71336] service-admin doesn't launch

[Daniel]

Public bug reported:

Binary package hint: gnome-system-tools

If I type
sudo services-admin 

I receive the following on the terminal:
(services-admin:5653): Liboobs-CRITICAL **: There was an unknown error communicating with the backends: The name org.freedesktop.SystemToolsBackends was not provided by any .service files
shift: 96: can't shift that many

I got a message box too, with a title and text (it is in hungarian, I
translate):

Settings cannot be loaded, you are not permitted to read system
settings.

Then I tried to restart the dbus service, as I have read somewhere in the forums:
sudo /etc/init.d/dbus start
