Comment:

 Hellooooooooooo !!

 Well, this fixes the bug but it also means that the object that is pickled
 does not necessarily correspond to the original one, as the new one admits
 multiple edges `^^;`

 What about setting ``multiple_edges = self._multiple_edges`` as it seems
 to be defined ? And there is an ``allow_loops()`` method for the other
 argument.
