TypeError: unorderable types because cur_token.node_split_penalty is None

[The-Compiler]

When running yapf over this code:

class CookieJar(RAMCookieJar):

    def purge_old_cookies(self):
        cookies = [c for c in self.allCookies()
                   if c.isSessionCookie() or c.expirationDate() >= now]

I get:

Traceback (most recent call last):

    "__main__", mod_spec)

I believe this should be fixed now. Reopen if not.
