Yes, this happens on our server, too. Actually, your post finally made me 
look in the right direction :-) Anyway, on our server, connections to
jabber.ccc.de fail as well as connections to gmail.com - same problem,
both services report different IP addresses for _xmpp-server._tcp than
for simple A records.

Could you post your quick-and-dirty fix, perhaps?

In the long run, this should be solved in the code, of course, as it's
obviously a bug. I'll try to come up with a patch.
