Broken link to og.css?

I noticed 404s in my error log for og.css, and did a bit of digging:

Location	http://[snip]/sites/all/modules/og/og.css
Referrer	http://[snip]/index.php?q=img_assist/header/uploading

I dug a bit and found line 373 in og.module:

drupal_add_css(drupal_get_path('module', 'og'). '/og.css');

Changing to this solved it:

drupal_add_css(drupal_get_path('module', 'og'). '/theme/og.css');

CVS says the file got moved eight days ago, so looks like this is just a leftover.
