Reset Prefix in panels_byterm

Hi there...
Pretty new in here so forgive me if this is the wrong place to post it or even if it has already been posted somewhere (though i had look around)
I think i found an error in function theme_views_bonus_panels_byterm_summary. When the depth is > 1, the prefix is been build...but its not reset so all next terms come with a prefix.
I just add before line 43 the following
$prefix='';
and works like a charm
so the function must be something like this

function theme_views_bonus_panels_byterm_summary($view) {
  theme_add_style(drupal_get_path('module', 'views_bonus') .'/views_bonus.css');
  // argument 0 must be a vocabulary ID
  $vid = $view->args[0];
  $tree = taxonomy_get_tree($vid);
  // group terms with their parent
  foreach ($tree as $term) {
    $cnt = taxonomy_term_count_nodes($term->tid);
    if ($term->depth > 1) {
      $prefix = _taxonomy_depth($term->depth-1). ' ';
    }
    $txt = array($prefix. l($term->name, "$view->real_url/$term->tid"). " ($cnt)");
    if ($term->depth == 0) {
      $parent_tid = $term->tid;
      $groups[$parent_tid]['header'] = $txt;
    }
    else {
      $groups[$parent_tid]['rows'][] = $txt;
    }
    $prefix=''; /* ADD THIS LINE */
  }
.....

and thank you for this nice module :D
