I tried latest master (573c5db) + graphenelib 1.1.10, and gon an error:

Traceback (most recent call last):

AttributeError: 'float' object has no attribute '_blockchain'

Here is the example code:

#!/usr/bin/env python

from bitshares import BitShares
from bitshares.asset import Asset
from bitshares.market import Market

bitshares = BitShares()
quote = Asset('RUDEX.GOLOS', bitshares_instance=bitshares)
base = Asset('RUBLE', bitshares_instance=bitshares)
market = Market(bitshares_instance=bitshares, base=base, quote=quote)

market.orderbook()
