abstractobject._set_data saves the data both to _json and to _data instance variables

I see that the SDK populates both _json and _data instance variables with the same information. Why would it do it?

    def _set_data(self, data):
        if hasattr(data, 'items'):
            for key, value in data.items():
                self[key] = value
        else:
            raise FacebookBadObjectError("Bad data to set object data")
        self._json = data

I suggest to hold the json only in one instance variable and retrieving from it when one asks for one key.

It seems like this issue has been open for more than a few months now. We have made many changes in the SDK since then, including releasing a new version. If you can repro your specific issue with the latest version of the SDK, please create a new issue or comment here with further details.
