Something like this (I am not on TDE now to test) should do the job I think:

                KURL default_red;
                default_red.setProtocol("help");
                default_red.setPath(   --> set path to default English version here <--   );
                default_red.setQuery(query);
                redirection(default_red);
                kdDebug( 7119 ) << "redirect to default " << default_red.url() << endl;
                redirect = true;
