Module causes RuntimeError, most methods unusable

Running in Python 3.4.3 on ubuntu linux.

Setup - copied directly from the Readme:

>>> from bitcoinrpc.authproxy import AuthServiceProxy, JSONRPCException
>>> import logging
>>> logging.basicConfig()
>>> logging.getLogger("BitcoinRPC").setLevel(logging.DEBUG)
>>> rpc_connection = AuthServiceProxy("http://bobby:propane@192.168.1.210:6969")

Using getinfo() causes an error:

>>> print(rpc_connection.getinfo())
DEBUG:BitcoinRPC:-1-> getinfo []

getaddressesbyaccount works:

>>> rpc_connection.getaddressesbyaccount('')
DEBUG:BitcoinRPC:-2-> getaddressesbyaccount [""]
DEBUG:BitcoinRPC:<-2- ["<snip>"]
['<snip>']

But not getbalance:

>>> rpc_connection.getbalance('')
DEBUG:BitcoinRPC:-3-> getbalance [""]

Should be fixed now that #39 is merged
