Defining link="file" in gallery shortcode throws errors

[Ipstenu]

To reproduce, put in a gallery manually via the shortcode (like this):

[gallery ids="1,2,3" link="file"]

And you get the following bad output:

Warning: trim() expects parameter 1 to be string, array given in /home/ipstenu/public_html/wp-includes/post-template.php on line 1486

If I remove link=file, it all works perfectly. Except no linking to files.
