Please stabilize.
This package is mainly used by gajim and I'm not sure if there are any bad interactions if an old gajim version uses a new python-nbxmpp (we had bugs with that before). gajim 1.2.2 is old enough to be stabilized and has no open bugs, so I think we can do both. So please don't stabilize this in isolation, but stabilize it together with gajim-1.2.2.
