I think this is more of a documentation issue than of a bug.
It may seems strange at first, but __metaclass__ and __class__ may be
different.
For instance, if M is metaclass
>>> class C(object): pass
>>> C.__metaclass__ = M
you get a class with metaclass hook equal to M, but C.__class__ is
still 'type'.
In you example, setting the __metaclass__ to 'type' does not change the
metaclass of
the created class, which is inherited from the base class. I suggest
you to file a documentation
bug. Unfortunately the basic documentation about metaclasses is a bit
lacking and you have
to discover many things by trial and errors.
