I was using Empathy earlier, however it crashed. When I tried to start it up again, I received an error about not being able to connect to the account manager.
The terminal posts the following output:
tom@blacknight:~$ empathy (empathy:29778): Gtk-WARNING **: Theme parsing error: gtk.css:2:63: Failed to import: The resource at '/org/gnome/adwaita/apps/nautilus.css' does not exist (empathy:29778): folks-WARNING **: Error preparing Backend 'telepathy': 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.
