[jitsi-dev] add contact error



Two issues here:

1. A few seconds after sending a request to "add contact" to an
XMPP/Jabber account, I get the attached exception. I tried a second
and third time and got as many exceptions.

2. The following day I noticed that the contact was successfully added
to my contact list, without requiring authorisation from me to be
added to their contact list.

This is strange, as with @jit.si Jabber accounts there is always an
automatic reverse-authorisation request sent when a buddy accepts my
authorisation request.
