Partial resolution of this issue was not in FOP but in the XSL stylesheet used.
I have XML data in the layout of:
<file>
<line></line>
<line></line>
<line></line>
<line></line>
<page>
<line>this</line>
<line>is</line>
<line>the</line>
<line>report</line>
<line>data</line>
</page>
<file>
And a stylesheet containing:
<?xml version="1.0" ?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:fo="http://www.w3.org/1999/XSL/Format";>
<xsl:output method="xml" indent="yes" />

I do not understand why this is happening, any suggestions
In general I am very pleased to see the progress that has been made with FOP,
it has served us well over the past 2 years in generating PDF contract notes. I
started to investigate an upgrade to see if we could generate larger files and
the rendering at every fo:page-sequence works well for us. Also I am pleased to
see the addition of PDF outlines. My thanks to the developers.

One of the things that changed in version 0.20.x of FOP is master-name
attribute on the page-sequence elements which became master-reference
instead. If you still have master-name attributes on your page-sequences, then
FOP often seems to throw a NullPointerException.

SC: thanks for this suggestion but FOP does actually warn me about this error.
