 One specific mp3 file was failing to attach, and it seems
 wp_insert_attachment is breaking with 0 returned, breaking update-
 attachment-metadata:

 wp-admin/includes/media.php, line 360:

 {{{

     // Save the data
     $id = wp_insert_attachment($attachment, $file, $post_id);
     if ( !is_wp_error($id) ) {
         wp_update_attachment_metadata( $id,
 wp_generate_attachment_metadata( $id, $file ) );
     }

 }}}

 id = 0, caused by these lines in wp-includes/post.php, around line 3351:

 {{{

 if ( false === $wpdb->insert( $wpdb->posts, $data ) ) {
             if ( $wp_error ) {
                 return new WP_Error('db_insert_error', __('Could not
 insert post into the database'), $wpdb->last_error);
             } else {
                 return 0;
             }
         }

 }}}

 In this case the documentation is wrong, it didn't return the post id.
