wp_ajax_get_comments fails on post.php

[c3mdigital]

Possibly related: #21101.
Related: #22039.
In the comments post meta box on post.php No comments found shows on posts that have comments.

The fail is happening at:

if ( !$wp_list_table->has_items() )
		wp_die( 1 );

The ajax response is always 1 with no comments returned.

Confirmed. Fixing ticket:21101:17 along with #22039 would fix this as well.
