Support for HTML in menu item title

Hi all,

i have tried to print out user picture(avatar) as a menu icon for a few hours. It works well with custom menu but not with superfish menu.

I used this code:

function OMEGASUBTHEME_menu_link(array $variables) {
  global $user;
  $element = $variables['element'];
  $sub_menu = '';

  if ($element['#below']) {
    $sub_menu = drupal_render($element['#below']);
  }
  $title = '';
  // Check if the user is logged in, that you are in the correct menu,
  // and that you have the right menu item
  if ($user->uid != 0 && $element['#theme'] == 'menu_link__user_menu' && $element['#title'] == t('My account')) {
    $element['#title'] = $user->name;
    // Add 'html' = TRUE to the link options
    $element['#localized_options']['html'] = TRUE;
    // Load the user picture file information; Unnecessary if you use theme_user_picture()
    $fid = $user->picture;
    $file = file_load($fid);
    // I found it necessary to use theme_image_style() instead of theme_user_picture()
    // because I didn't want any extra html, just the image.
    $title = theme('image_style', array('style_name' => 'thumbnail', 'path' => $file->uri, 'alt' => $element['#title'], 'title' => $element['#title'])) . $element['#title'];
  } else {
    $title = $element['#title'];
  }
  $output = l($title, $element['#href'], $element['#localized_options']);
  return '<li' . drupal_attributes($element['#attributes']) . '>' . $output . $sub_menu . "</li>\n";
}

from here

What did i wrong? Can you help me please? Thanks :-)
