Manage Translators Page Unavailable After Adding Languages

We're having a similar problem. Not only Manage Translators (admin/content/translation-management/manage-translator) shows a blank page but also the Dashboard (admin/content/translation-management/dashboard) does.

Weird though is that when viewing a specific node in the dashboard (e.g. admin/content/translation-management/dashboard?nid=666), the dashboard page gets displayed properly. When using link Show all documents (points to admin/content/translation-management/dashboard) the white screen appears again.

Well, I figured that one's running out of memory at building permission (user_access) while displaying page Manage Translators (admin/content/translation-management/manage-translator):

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 31 bytes) in /modules/user/user.module on line 517

This is basically caused by function _icl_translate_get_non_translators() where all active users are fetched and loaded (user_load) and thus user_access is executed:

/**
 * Fetches users that aren't 'translators'.
 * @todo Check if Drupal has this function (not found).
 */
function _icl_translate_get_non_translators() {
  $rid = variable_get('icl_translate_role', 0);
  $q = _icl_wrapper_db_query("SELECT uid FROM {users} WHERE status=%d ORDER BY name", 1);
  $rows = array();
  while ($r = db_fetch_array($q)) {
    if ($r['uid'] == 0) {
      continue;
    }
    $user = user_load($r['uid']);    
    if (!_icl_translate_is_translator($user)) {
      $rows[] = $user;
    }
  }
  return $rows;
}

Quick fix might be increasing the memory (use ini_set in settings.php - see below) but I dare say this can't be the final solution:

# Increase Memory Limit
ini_set('memory_limit', '512M');

I've modified this so that it doesn't load all the user's information into memory, it only loads the information it needs.
