As far as I can tell -- yes. If I am connected to google talk, and I try 
and add as a contact someone on my DJabberd server, then the dialback 
fails. For me, this is quite reproducible.

It appears that google sends a 'not-authorized' in response to DJabberd 
sending the '<stream:features></stream:features>' stanza. Indeed, from a 
packet capture, this looks as though it is exactly what is happening. 
The packet flow is:

TX: <?xml version="1.0" encoding="UTF-8"?><stream:stream to='gmail.com'
