When I try to join a password protected conference, I send:
<presence xml:lang="en" to="[EMAIL PROTECTED]/chrism">
<x xmlns="jabber:x:avatar">
<hash>4c2dfaf57559ffe57e8dd382f0799f1ad5e7ae80</hash>
</x>
<x xmlns="http://jabber.org/protocol/muc">
<password>chris</password>
</x>
</presence>
The presence of two "x" nodes in there, causes the server to reply back
with an error.
If I eliminate the Avatar node, things are fine.
This likely means that MU-Conference isn't checking for namespaces on
the "x" node, which seems like a pretty serious bug.
