In general, the error means that you attempted to index an object that doesn't have that functionality. You are trying to subscript an object which you think is a list or dict, but actually is None. NoneType is the type of the None object which represents a lack of value, for example, a function that does not explicitly return a value will return None. 'NoneType' object is not subscriptable is the one thrown by python when you use the square bracket notation object[key] where an object doesn't define the __getitem__ method . e.g.: http://net-informations.com/python/err/nonetype.htm

Reason: This has had open comments for some time now and the fix doesn't seem correct. I'm going to abandon this in case someone else wants to take a stab at resolving this.
