Every so often the terminal comes up with a corba error "
Adding client to server's list failed, CORBA error: IDL:omg.org/CORBA/COMM_FAILURE:1.0", as shown in the image.
The solution seems to be to delete
rm ~/.gconfd/saved_state ~/.gconfd/saved_state.tmp
And then to kill gconfd
Seems to work for me, but I can't guarantee that it won't do anything nasty to your system.
