Comments_template filter not working

add_filter(‘comments_template’, array( $this, ‘add_socialcomments_tmplate’));

There’s something wonky here.. the filter isn’t hitting, not sure why, when I try to die(“a message”); I get a 500 http error response? Its my theme either has its happening in both the twentytwelve and twentythirteen themes.. could be a bug in 3.6?

I’m going to do some more testing here, let me know if you can shed any light on this please.

Best,
