Not sure if this is a bug.
I was attempt to construct a Q object that wouldn't ever match anything
(an API calls for a Q object to be returned, but certain situations call
for nothing to be matched by it). I initially figured `~ Q()` would do the
trick, but that matches everything, just like a plain `Q()`.
(I ended up using `Q(pk__isnull=True)`, which is a hack but seems to be
OK.)
