programlistings, double spaced?

I'm using programlisting, with xincluded content.
What is already a long listing is now double spaced when
I look at the PDF output (docbook 5).

Anyone resolved this please?

The fo is

<?xml version="1.0" encoding="utf-8"?>
<fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format">
 
  <fo:layout-master-set>       
    <!--  -->
    <!-- Page descriptions -->
    <!-- SPM 1, basic page  All regions
present-->                        
 <fo:simple-page-master


Note the (additional I think) & # x D ; at each line end?

How to get rid of these?
Linux based if it makes a difference.
