Hmm, that is at least supposed to work.  That it doesnt, is sort of worrying.

"GNOME", "guess", and "smart", in one sentence.  I am not impressed :-)

What kernel version and bluetooth stack version are you using, actually?

Have you tried cleaning out the /var/lib/bluetooth/HCI_ADDRESS directory
already?
On my laptop, I have a bug in the bluetooth stack (kernel 3.2) which
leads to new connections to my Handy Tech Braille Star no longer being
made after about a wek or two of usage.  I have not determined what happens
exactly, but it must be something around link-keys.  So if I delete all
the state information in /var/lib/bluetooth/HCI_ADDRESS, suddenly I can
connect to my Braille Star again.  Maybe you have run into a similar
issue?
