autoproxy example only works with pickle

The autoproxy example does not work out of the box. The server runs, but the 
client throws a traceback:

$ python client.py 
enter factory server object uri: PYRO:example.autoproxy@localhost:64340
/Users/ach/projects/pyrotest/lib/python2.7/site-packages/Pyro4/core.py:167: 
UserWarning: HMAC_KEY not set, protocol data may not be secure
  warnings.warn("HMAC_KEY not set, protocol data may not be secure")
Creating things.

    return self.recreate_classes(serpent.loads(data))

    return self.dict_to_class(literal)
  File "/Users/ach/projects/pyrotest/lib/python2.7/site-

    raise Pyro4.errors.ProtocolError("unsupported serialized class: 
"+classname)
Pyro4.errors.ProtocolError: unsupported serialized class: Thingy
$


Changing the serializer to pickle makes the example work. Changing it to 
json or marshal leads to similar tracebacks.
