Comment:

 I could trace the problem to `admin-ajax.php`. The function that creates
 the link for the upload has a `global $post_ID`. However, the `set-post-
 thumbnail` case have a `$post_id` (yes, 2 different variable names).

 As a first attempt to fix it, just adding `$post_ID = $post_id;` below
 line 1465 fixes the bug. Another option (way more cool) is changing the
 variable name in `set-post-thumbnail`; but there's no clue if this bug
 could flip (ie. : another function has `global $post_id`)
