Pheww.. that actually did it. Looks like it's fixed now. Google assumes 
that people subscribing to Apps Teams Edition don't have an xmpp service 
  already running. That kind of dangerous, especially if activating the 
domain doesn't give you access to the management pages right away.

Google should check by testing the SRV entries if an  XMPP service is 
already provided by the domain before activating a non federated one 
causing internal routing problems at google.
