fix array in array Subscribed Events, for example in https://github.com/symfony/HttpKernel/blob/master/EventListener/RouterListener.php#L115 :

    public static function getSubscribedEvents()
    {
        return array(
            KernelEvents::REQUEST => array(array('onKernelRequest', 32)),
        );
    }
