No.

I think the problem is I have two gatekeepers defined.  In the accounts
window one (gk1) is selected as active and one (gk2) is not.

At startup I see:

08:45:49 Started GnomeMeeting 1.9.0 for user malcolm
08:45:50 Registered to gk1.abc.blah
08:45:50 Unregistered gk2.abc.blah

Now gk2 was never registered.  Perhaps gm is seeing that gk2 is
unselected, goes and unregisters gk1?
