 > If this check isn't working, it could mean that
 `jarabe.model.friends.get_model` isn't working properly... I don't see a
 `__call__()` method in `jarabe.model.friends.Friends`, but I don't know
 enough about `gobject.GObject` to know if this is a problem.

 get_model() implements a Singleton pattern. The first time you invoke it,
 it builds a Friends object through the constructor and stores a reference
 to it in the global variable _model, which is used in future calls.
