[fw-general] problem with headMeta()->appendName() not having end of tag in html

[water]

If I create a meta tag via:
 $this->nav->headMeta()->appendName('y','1234');

and on the layout have:
<?=$this->headMeta(); ?>

The outputted html will be 

<meta name="y" content="1234" >

rather than:
<meta name="y" content="1234" />

I also have the same problem with css pages:
<link href="/static/css/profile.css" media="screen" rel="stylesheet" 
type="text/css" >

Any way to get the closing tag? Probably something obvious I'm missing.

thanks,

jonathan
