Comment(by mtdewvirus):

 Replying to [comment:2 filosofo]:
 > What are the unexpected results?  `wp_get_attachment_image` calls
 `wp_get_attachment_image_src`, which calls `image_downsize`, and
 `image_downsize` performs that check already.  I don't see how you would
 get anything other than an empty string or `false` already.

 Run it on a video post_id and you get an image returned. If
 `image_downsize` fails in `wp_get_attachment_image_src`, the function
 still tries to get an image by using `wp_mime_type_icon`.
