annotations and charms not working apiserver

applies to charms and annotations facades

        return self.rpc._rpc({
            "Type": "Charms",
            "Request": "List",
            "Params": {"Names": names}})

gets

jujuclient.EnvError: <Env Error - Details:
 { u'Error': u'unknown object type "Charms"',
    u'ErrorCode': u'not implemented',
    u'RequestId': 1,
    u'Response': { }}

same code works for every other facade, using a trunk checkout. I do see the Charms facade in the login data, ie.
