Yes, thanks. Whoever got bit by this is either getting an exception or not the intended behavior (due to failed string comparison). I doubt anybody is relying on the new type checking since it's not documented. If they are, they are probably just doing:

    def callback(name, names):
        if not isinstance(name, str):  # bugfix 3.8
            name = name.name
        ...
