tpl.php file generating wrong path for icons

When the config setting save, they generate a path for icons that start with http://default/sites/default/files/menu_icons, even though the CSS file and icon files are stored in the same directory.

I did a quick fix in the menu_icons_css_item.tpl.php file from

background-image: url('<?php print $path ?>')

to

background-image: url('menu_icon_<?php print $mlid ?>.png')

which seems to work for now.
