How to use Trackbacks in r1039

I am trying to get trackbacks to work in my r1039. I installed the patch
from the link below and I see the trackback field when posting, but I
don’t see my comment in the blog which I sent the trackback. The blog
I’m trying to send trackbacks supports them.

This is the patch (I also updated it)
http://ruby.tower-net.de/index.html/articles/2006/05/02/typo-patch-trackback-support

Is it anybody able to explain me how it works?

Thanks,
