Search users - return nothing

Hi - I know your'e busy and really don't hope i file smt wrong or repost here. But it seems the search filter doesn't work for users. On a new Drupal 6.12 installation i create a "user view", add "username" to fields and "search term" to filters and expose it with all the default options checked. I search, and nothing return.

Query:

SELECT users.uid AS uid,
   SUM(search_index.score * search_total.count) AS score,
   users.name AS users_name
 FROM users users 
 LEFT JOIN search_index search_index ON users.uid = search_index.sid
 LEFT JOIN search_total search_total ON search_index.word = search_total.word
 WHERE (search_index.word = 'simon') AND (search_index.type = 'users')
 GROUP BY search_index.sid, uid, users_name
 HAVING COUNT(*) >= 1

View:

$view = new view;
$view->name = 'user_search';
$view->description = 'user_search';
$view->tag = '';
$view->view_php = '';
$view->base_table = 'users';
$view->is_cacheable = FALSE;
$view->api_version = 2;
$view->disabled = FALSE; /* Edit this to true to make a default view disabled initially */
$handler = $view->new_display('default', 'Defaults', 'default');
$handler->override_option('fields', array(
  'name' => array(
    'label' => 'Name',
    'alter' => array(
      'alter_text' => 0,
      'text' => '',
