When attempting to move a page, I get an internal error with the following reason:
[54a0b04b1ae5eaa1b6018cc1] /w/index.php?title=Special:MovePage&action=submit TypeError from line 123 of /var/www/live/w/extensions/ArticleRatings/ArticleRatingsHooks.php: Argument 5 passed to AreHooks::onTitleMove() must be an instance of Status, none given, called in /var/www/live/w/includes/Hooks.php on line 177

MasterAS on Bricki notified me of this (so it's not just me with the problem), and it appears to affect all namespaces.
