GTalk replies:

    * error type='modify'
        * bad-request xmlns='urn:ietf:params:xml:ns:xmpp-stanzas'
        * text xmlns='urn:ietf:params:xml:ns:xmpp-stanzas'
            "candidate has address of zero"

Since none of your candidates actually have 0 in their address, my guess is
that what it really means is that GTalk doesn't support IPv6, and is
mis-parsing the two IPv6 candidates at the top as an IPv4 address of 0.0.0.0.

If I'm right, then we could maybe work around this by omitting IPv6 candidates
when using the http://www.google.com/transport/p2p dialect of Jingle?
