panelizer_update_7300 throws error if no records found

same :(

Oh, now I see what the problem is. Duh, Damien.

Please test this out, it should solve the problem.

#7 Worked! Thx!

Please don't change the issue status to "fixed", I haven't committed the change yet :)

Thank you both for reviewing the patch, I've committed the fix and it'll be available in the -dev snapshot shortly, and the v3.3 release.

foreach ($entity_types as $entity_type) {
    // Get the default panelizer names for the entity type.
    $default_names = array();
    $entity_info = entity_get_info($entity_type);
    if (!empty($entity_info) && !empty($entity_info['bundles'])) {
      foreach ($entity_info['bundles'] as $bundle => $bundle_info) {
        $var_name = 'panelizer_defaults_' . $entity_type . '_' . $bundle;
        $settings = variable_get($var_name);
        if (!empty($settings) && !empty($settings['view modes'])) {
          foreach ($settings['view modes'] as $view_mode => $config) {
            $default_name = implode(':', array($entity_type, $bundle, 'default'));
            if ($view_mode != 'page_manager') {
              $default_name .= ':' . $view_mode;
            }
            $default_names[] = $default_name;
          }
        }
      }
    }

    // Delete panelizer records that have one of the default names.
    $deleted = db_delete('panelizer_entity')
      ->condition('name', $default_names, 'IN')
      ->condition('entity_type', $entity_type)
      ->execute();

I've faced the same error and obviously this isn't complete. I think the above code doesn't make sense. The delete process is supposed to be within for loop? On top of that, the error occurs when deleting panelizer_entity with empty default_names and/or null entity_type. I think type checking is necessary.
