	Sounds like a bug ..

	A debug log might help to figure out what's going on. I think the best
way to get that is:

  1) gconftool-2 -s /desktop/gnome/remote_access/enabled -t bool false

  2) killall vino-server

  3) VINO_SERVER_DEBUG=1 /usr/libexec/vino-server

  4) gconftool-2 -s /desktop/gnome/remote_access/enabled -t bool true

	and then connect.
