White screen with text in settings page

Just to add that attached is what I see in IE

Update: Only seems to happen with the Dashboard module is on

Update: I can also replicate this on a clean install with the Dashboard module enabled, using Drupal version 7.8

Update: It seems like the dashboard_system_info_alter() function in dashboard.module is the problem, if I remove this function, it works fine

<?php
/**
 * Implements hook_system_info_alter().
 *
 * Add regions to each theme to store the dashboard blocks.
 */
function dashboard_system_info_alter(&$info, $file, $type) {
  if ($type == 'theme') {
    // Add the dashboard regions (the "inactive" region should always appear
    // last in the list, for usability reasons).
    $dashboard_regions = dashboard_region_descriptions();
    if (isset($dashboard_regions['dashboard_inactive'])) {
      $inactive_region = $dashboard_regions['dashboard_inactive'];
      unset($dashboard_regions['dashboard_inactive']);
      $dashboard_regions['dashboard_inactive'] = $inactive_region;
    }
    $info['regions'] += $dashboard_regions;
    // Indicate that these regions are intended to be displayed whenever the
    // dashboard is displayed in an overlay. This information is provided for
    // any module that might need to use it, not just the core Overlay module.
    $info['overlay_regions'] = !empty($info['overlay_regions']) ? array_merge($info['overlay_regions'], dashboard_regions()) : dashboard_regions();
  }
}
?>

Anyone else getting this?

I've made some progress on this, but I still need some help. I've found the code causing the problem, in alpha/includes/theme-settings-structure.inc, line no 228...

<?php
    $form['alpha_settings']['structure'][$section][$zone]['regions'][$region]['alpha_region_' . $region . '_position'] = array(
      '#type' => 'weight',
      '#delta' => 50,
      '#title' => t('Position'),
      '#default_value' => $item['position'],
        '#states' => array(
          'visible' => array(
            ':input[name="alpha_zone_' . $zone . '_order"]' => array('checked' => TRUE),
          ),
        ),
    );
?>

If I change the delta value to 18, the problem goes away, anything higher than 18 causes the error again.

<?php
      '#delta' => 18,
?>

My guess is that changing this shouldn't break anything, can someone confirm?
