Comment 4 for bug 151937

Ok, here's the error i get:

Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

Duplicating the bug was meant to help you to get a reference, as you wrote in https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/138277

> closing the bug, if somebody still get an issue you should open a new bug about it

So here it is. Backtrace will follow soon
