Theme without comments.php is depreciated notice on single posts.

 Again with my WP_Debug stuff.  

[WP should be defaulting to /comments.php](link=http://codex.wordpress.org/Function_Reference/comments_template) for the comments_template call.  On unformatted single posts you'll get notices (see below) about needing this file.   

If you want to concretely reference the file, '/comments.php' also fixes this.  Weird.
