TypeError: confirm_delivery() got an unexpected keyword argument 'callback'

The issue is its using a BlockingConnection and with a blocking connection it does not allow for a callback:

/usr/local/lib/python2.7/dist-packages/pika-0.9.8-py2.7.egg/pika/adapters/blocking_connection.py(431)confirm_delivery()
