#89 jabber-muc-invite failing silently

[Duncan Bayne]

I'm using the following code to create a new Google Hangouts group chat:

(defun jabber:google-groupchat-create ()
  (interactive)
  (let ((group (apply 'format "private-chat-%x%x%x%x%x%x%x%x-%x%x%x%x-%x%x%x%x-%x%x%x%x-%x%x%x%x%x%x%x%x%x%x%x%x@groupchat.google.com"
                      (mapcar (lambda (x) (random x)) (make-list 32 15))))
        (account (jabber-read-account)))
    (jabber-groupchat-join account group (jabber-muc-read-my-nickname account group) t)))

This works, and I can use jabber-muc-invite to invite people from my Hangouts roster.

Unfortunately, they never see the invitation, and no errors are displayed in the groupchat buffer, or logged to *Messages*.

I'm running jabber-20160124.552, installed from ELPA.
