Undefined index show_messages

In template.php, the page_process hook has a switch case asking for what seems to be the wrong variable:
Line 237

<?php
case 'seed_messages':
        if ($seed['show_messages']) {
?>

Inspecting with Devel, seems to be a different name:

<?php
case 'seed_messages':
        if ($seed['messages_as_block']) {
?>
