    def get(self, section, key,raw=True,fallback='rest'):
        try:
            return super(KazamConfig,self).get(section, key,raw=raw,fallback=fallback)

allows it to start. This matches the keyword parameters with configparser and calls the superclass method with the keyword parameters. They should be ignored by whatever calls the KazamConfig get method, but if anything else calls get on the KazamConfig class expecting to get the method from the superclass it will also work.
