Fresh install of 11.4 Gnome livecd version a few days ago. Just did a normal daily update and now nautilus does not work.
The error message from terminal reads
(nautilus:7726): Unique-DBus-WARNING **: Error while sending message: 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.
Also other errors include, the icons on the panel has re-arranged themselves, as well as unable to right click on the desktop.
The only additional app installed was gDesklets, but I removed that after a few minutes.
Any ideas, thanks.
