Statistics API has changed slightly from it's pre-release state resulting in errors when reading backend capabilities:

KeyError: 'statistics'
The system information (capacity, used space) is not available as member of the 'statistics' field in the Quobyte backend but as direct members of the message. This means calls trying to read the key 'statistics' fail as this field is not available. Need to read the capacity and used fields directly.
Simple fix, will upload shortly
