It's a static function, so it fatal errors when $this is referenced. I was initially just going to change all the references of $this->meta_key to self::$meta_key and add that static property, but seeing it's a dynamic meta_key value, it's likely not the right solution.
Edit:
Running WP 3.5 and latest master branch of this plugin.
