This seems like it could be user error, but the traceback doesn't provide useful information on where the problem could be. The relevant class is at the following URL.

Please let me know if more information is required.

Looking at the traceback and your code, configparser is calling 'get', expecting to call its own get method (that takes a 'raw' keyword), but instead is calling the get on your subclass, which doesn't take a 'raw' keyword.  

Since this appears to be example code, probably what you should do to fix this is remove those get methods.  Your 'default' is spelled 'fallback' in Python3.2 configparser and does the same thing your code does.
