 When I try to embed a url like http://webcompetent.org/?p=6343, Wordpress
 tries to embed the page with the id 6343 from my own site.

 This is because the function url_to_postid is called via the filter
 wp_filter_pre_oembed_result. There is not checked as first whether it is
 the url of the own side. Therefore supplies
 {{{#!php

         // First, check to see if there is a 'p=N' or 'page_id=N' to match
 against
         if ( preg_match('#[?&](p|page_id|attachment_id)=(\d+)#', $url,
 $values) )       {
                 $id = absint($values[2]);
                 if ( $id )
                         return $id;
         }
 }}}

 the ID of the remote page as a local ID.
