I had a similar problem when I unregistered my jabber.org account by error
with a beta version of a client. The subscription was out of sync, and
still is for
many of my contacts, because server don't route my subscription requests.
The only solution is to delete the contact on both sides and subscribe again.

right, this is how it should (MUST) be done.
