Broken checkbox "Allow registering users to sign up for nodes from the user registration form"

I hacked together a fix, if you comment out the following code in signup.module (sites/all/modules/signup. line 707-737) the signups don't appear on the user registration page:

// Get a list of nodes that should appear on the user registration form.
$query = db_select('node', 'n');
$alias = $query->join('signup', 's', 'n.nid = s.nid');
$query->fields('n', array('nid'));
$query
->condition("n.status", 1)
->condition("{$alias}.user_reg_form", 1)
->condition("{$alias}.status", 1);
$query->addTag('node_access');
$nids = $query->execute()->fetchCol();

// Allow other modules to alter the list of nids.
drupal_alter('signup_user_reg_nids', $nids);
// If there is at least one node, add the Signup fieldset.
if (!empty($nids)) {
$form['signup'] = array(
'#type' => 'fieldset',
'#title' => t('Event signup'),
'#tree' => TRUE,
'#description' => t('You will be automatically signed up once your account is created.'),
);
// Each node gets a checkbox.
foreach ($nids as $nid) {
$node = node_load($nid);
$form['signup'][$nid] = array(
'#type' => 'checkbox',
'#title' => theme('signup_node_title', array('node' => $node)),
'#default_value' => 0,
);
}
}
