As the text in the error indicatesI, this is caused when a client says "I
want to connect to jabber.org", except the client is connected to, e.g.,
Google's servers (which don't serve jabber.org).  Or, in this case, the
client says "I want to connect to the XMPP host 'talk.google.com'", except
the XMPP service is on 'gmail.com'.

From the XMPP soon-to-be-published-as-standard core internet-draft
(rfc3920bis):
4.9.3.6.  host-unknown

   The value of the 'to' attribute provided in the initial stream header
   does not correspond to an FQDN that is serviced by the receiving
   entity.

   (In the following example, the peer specifies a 'to' address of
   "example.org" when connecting to the "im.example.com" server, but the
   server knows nothing of that address.)

* Amusingly, that's not at all an error message I'd want to present to an
end-user, and is making me rethink changing the jabber prpl to prefer those
messages to the built-in ones
