WordPress Comment Bug

Hi, I just find a comment bug with wordpress which I think is there for a ling site, may be since v2.7+ but never actually fixed. Any idea how to fix or report it?

Bug Details/ Reproduce process

Inside your theme while fetching your comments after have_comments() try to fetch comments only by using wp_list_comments( array( "type" => "comment") ) and then below check if trackback exists and if they do print the trackbacks separately using wp_list_comments( array( "type" => "pings") ).

Now add a bunch of comments on any of your blog post which also have some trackbacks. Add more than 60 – 70 comments on that post. and from settings enable comment pagination option. So that comments get divided into several comment pages. If you are thinking this is never going to happen in real life, let me tell you I have blog posts which has more than 2.500 comments in it and none of them are spam comments.

Now, after you enable the comment pagination, visit your blog page link i.e. example.com/some-post/ and you will see the trackbacks below your comments as it should show up now start navigation through your comment pagination, you will see the following –

1. Trackback is showing on the normal blog post link
2. Trackbacks also showing for /comment-page-1/

But when you will move further from comment page 1 you will only see the heading i.e. Trackback or whatever you have set, but not the actual trackbacks. This problem is also present in genesis theme, earlier I though it was a genesis bug but while developing a non genesis wordpress there I understood that it is actually a wordpress core bug.
