no attribute 'volume_step'

Running Ear Candy 0.9 from the devt PPA under Maverick, results in the following appearing looping in the console:

Traceback (most recent call last):
  File "/usr/lib/pymodules/python2.6/earcandy/EarCandy.py", line 283, in __adjust_volumes
    if sink.set_volume():
  File "/usr/lib/pymodules/python2.6/earcandy/SinkInput.py", line 75, in set_volume
    step_volume = current_volume + self.client.volume_step
AttributeError: 'NoneType' object has no attribute 'volume_step'

The app works but this is a minor annoyance.
