html problem on menus

First, thanks for this module, it's very useful.

I use your module to show the sitemap of my site, and I have 3 menus.

When viewing the sitemap page, my blocks were misplaced : it comes from an excess div ending on line 170 of sitemap.module :

function theme_site_map_box($title, $content, $class = '') {
  //return  '<div class="sitemap-box '. $class .'"><h2 class="title">'. $title .'</h2><div class="content">'. $content .'</div></div>';
  return  '<div class="content">'. $content .'</div><div>';
}

suppresses one of the

in the return

:
return '<div class="content">'. $content .'</div>';

and it's ok !
