Comment 16 for bug 1170832

Thanks will update patch.

Disco requests/responses attached for future reference.

Facebook's beta server for me returns the following on a disco request

<!-- sent -->
<iq id="327894361669" to="beta.chat.facebook.com" type="get" xmlns="jabber:client">
 <query xmlns="http://jabber.org/protocol/disco#info"/>
</iq>

<!-- received -->
<iq id="327894361669" type="result" xmlns="jabber:client">
 <query xmlns="http://jabber.org/protocol/disco#info">
  <identity category="server" type="Facebook XMPP"/>
  <feature var="http://jabber.org/protocol/commands"/>
  <feature var="http://jabber.org/protocol/chatstates"/>
  <feature var="vcard-temp"/>
 </query>
</iq>

requesting disco info chat.facebook.com is the same

<!-- sent -->
<iq id="67671632942" to="chat.facebook.com" type="get" xmlns="jabber:client">
 <query xmlns="http://jabber.org/protocol/disco#info"/>
</iq>

  <feature var="http://jabber.org/protocol/commands"/>
  <feature var="http://jabber.org/protocol/chatstates"/>
  <feature var="vcard-temp"/>
 </query>
</iq>

I know Facebook rolls out services gradually, and some of my user's are hitting the same error that I am currently getting with the beta service so I suspect this will hit most user's soon.
