Undefined index: nid in webform_localization_delete_translate_strings

When creating a node of a webform enabled type,
and deleting it, you get this error.

Undefined index: nid in webform_localization_delete_translate_strings

Easy fix, change:

/**
 * Implements hook_node_delete().
 */
function webform_localization_node_delete($node) {
  if (!in_array($node->type, webform_variable_get('webform_node_types'))) {
    return;
  }

  module_load_include('inc', 'webform_localization', 'includes/webform_localization.i18n');
  // Deletion of webform and emails translatable properties.
  webform_localization_delete_translate_strings($node);
  // Delete webform localization configuration record.
  db_delete('webform_localization')->condition('nid', $node->nid)->execute();
}

/**
 * Implements hook_node_delete().
 */
function webform_localization_node_delete($node) {
  if (!in_array($node->type, webform_variable_get('webform_node_types'))
    || empty($node->webform['components'])) {
    return;
  }

  module_load_include('inc', 'webform_localization', 'includes/webform_localization.i18n');
  // Deletion of webform and emails translatable properties.
  webform_localization_delete_translate_strings($node);
  // Delete webform localization configuration record.
  db_delete('webform_localization')->condition('nid', $node->nid)->execute();
}

(added empty($node->webform['components']) )
