According to this userLeft() takes 3 arguments. Your traceback is interesting.

[Michael Otteneder (m-otteneder)]

We did not overwrite userLeft() properly. lib.core contains this:
    def userLeft(self, user, channel, reason):
        """Called when someone has to go."""
        for plugin in self.plugins:
            plugin.user_part(self, user, channel, reason)

As you can see our userLeft() really requires 4 parameter.
