Menu items for user categories cannot be translated

Hi,

Just noticed in Drupal 6.15 that menu items for user categories, those that generate secondary tabs, cannot be translated. The problem is that these menu items use check_plain for the title callback, so t() is never involved.

Here's the code in user.module, user_menu() that build these items:

        $items['user/%user_category/edit/'. $category['name']] = array(
          'title callback' => 'check_plain',               // This is the problem !!!
          'title arguments' => array($category['title']),
          'page callback' => 'user_edit',
          'page arguments' => array(1, 3),
          'access callback' => isset($category['access callback']) ? $category['access callback'] : 'user_edit_access',
          'access arguments' => isset($category['access arguments']) ? $category['access arguments'] : array(1),
          'type' => MENU_LOCAL_TASK,
          'weight' => $category['weight'],
          'load arguments' => array('%map', '%index'),
          'tab_parent' => 'user/%/edit',
          'file' => 'user.pages.inc',
        );

Instead, I think it could be like this:

        $items['user/%user_category/edit/'. $category['name']] = array(
          'title callback' => '_user_sanitize_category',               // Use a different title callback !!!
          'title arguments' => array($category['title']),
          'page callback' => 'user_edit',
          'page arguments' => array(1, 3),
          'access callback' => isset($category['access callback']) ? $category['access callback'] : 'user_edit_access',
          'access arguments' => isset($category['access arguments']) ? $category['access arguments'] : array(1),
          'type' => MENU_LOCAL_TASK,
          'weight' => $category['weight'],
          'load arguments' => array('%map', '%index'),
          'tab_parent' => 'user/%/edit',
          'file' => 'user.pages.inc',
        );

And then, add the following function somewhere in user.module:

function _user_sanitize_category($title) {
  return check_plain(t($title));
}
