If you use an itemlist in a skin, it appears that the comments get confused. The skins/_feedback.php page uses a side effect to get the post id, not the right way.
To Fix:
skins/_feedback.php line 90 change to:
$CommentList = & new CommentList( 0, implode(',', $type_list), array(), $Item->ID, '', 'ASC' );
Another comments bug is that if comments are disabled for the blog as a whole, it still says "No comments on this post yet", which is silly.
To fix, line 52
if( $Item->can_see_comments() && $Blog->allowcomments != "never" )
Thanks for the fix. I'll commit it.
I've applied the [[$Blog->allowcomments != "never"]] patch to Item::can_see_comments() directly though.
