[Plugin: WP-PostViews] Notice error when debug is turned on

I am getting the following notice error when I have debug turned on:

Notice: Undefined index: postviews_id in /wordpress/wp-content/plugins/wp-postviews/wp-postviews.php on line 646

Line 646 is currently set as:

$post_id = intval($_GET['postviews_id']);

To remove the notice error, it just needs to be changed to:

$post_id = isset($_GET['postviews_id']) ? intval($_GET['postviews_id']) : 0;

Found another one:

Notice: Undefined index: views in /wordpress/wp-content/plugins/wp-postviews/wp-postviews.php on line 67

Line 67:

$post_views = intval($post_views['views'][0]);

Should be:

$post_views = isset($post_views['views'][0]) ? intval($post_views['views'][0]) : 0;

Hope that helps!
