TypeError: can only concatenate list (not "str") to list

Fix:

    def get_scope(self):
        """Return list with needed access scope"""
        return (self.DEFAULT_SCOPE or '') + \
               self.setting('SCOPE', '')

SOCIAL_AUTH_*_SCOPE setting must be a list, not a string, if it's a single scope, then define it as a single item list.
