libvirt users - Oct 2014 - Error starting Virtual Machine Manager: Failed to contact configuration server...

Hi all!
Do you have any idea about the following error message from virt-manager. I was
trying to start it with "sudo virt-manager". Do you think I can fix
this by simply restarting libvirtd?
Regards,
Allen

Error starting Virtual Machine Manager: Failed to contact configuration server;
some possible causes are that you need to enable TCP/IP networking for ORBit, or
you have stale NFS locks due to a system crash. See
http://projects.gnome.org/gconf/ for information. (Details -  1: Could not send
message to GConf daemon: 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.)
