Attachment taxonomies, $term->count not working

[paddelboot]

Backend:

1. Register an attachment taxonomy
2. Create a taxonomy term
3. Upload an attachment and check the box of the newly created term, save.
4. Go to the attachment taxonomie's overview
5. Under "Media", it shows 0
6. Click on "0", and you should see the attachment in the overview.

Code:

register_taxonomy( 'attachment_directories', 'attachment' );

$term = wp_insert_term( 'parent', 'attachment_directories' );

$args = array(
			'post_title' => 'dummy-attachment',
			'post_content' => '',
			'post_status' => 'inherit',
			'post_mime_type' => 'image/jpeg',
			'post_author' => '1'
		);

$id = wp_insert_attachment( $args );

wp_set_object_terms( $id, $term[ 'term_id' ], 'attachment_directories' );

$args = array(
			'hide_empty' => TRUE,
			'fields' => 'ids'
		);

$non_empty_directories = get_terms( 'attachment_directories', $args );

//$non_empty_directories is an empty array(), but it should return the ID of the 'parent' term.

Of course last line should be:

$non_empty_directories = get_terms( 'attachment_directories', $args );

instead of:

$non_empty_directories = get_terms( 'attachment_directories', $args3 );

[paddelboot]

It seems to have something to do with whether the attachment is attached to a post or other object or not.

• Editing an unattached media file and selecting a taxonomy term for it does not, after saving, increase this term's counter
• Un-selecting the taxonomy term, saving the media file, attaching the media file to something, and again selecting the taxonomy tag does, after saving, increase the term's counter

Is this in any way wanted?
