[xsl] Core Dump running xsltproc

["Paul Moloney" <paul_moloney@xxxxxxxxxxx>]

I hope someone can help me, I'm a relative newbie to this. I'm 
following the tutorial given at this page:

http://www.codeproject.com/winhelp/docbook_howto.asp

All is well until I reach the section on customising the style sheet. 
I'm using the

following files:

simple.xml

===============================================

<?xml version="1.0"?>

<!DOCTYPE book PUBLIC "-//OASIS//DTD DocBook XML V4.2//EN"

"http://www.oasis-open.org/docbook/xml/4.2/docbookx.dtd"; >

<book>

<title>Simple Book</title>

<titleabbrev>Simple</titleabbrev>

<preface><title>Introduction</title>

<para>

Hello! Here's an introduction!

</para>

</preface>

<chapter><title>On Foo's</title>

<para>

Stuff about Foo's goes here.

</para>

</chapter>

<chapter><title>On Bars's</title>

<para>

Stuff about Bars's goes here.

</para>

</chapter>

</book>

===============================================

simple.xsl:

===============================================

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";

version="1.0">

<xsl:import 
href="/home/pmoloney/docbook-xsl-1.69.1/htmlhelp/htmlhelp.xsl"/>

</xsl:stylesheet> ===============================================

(I've check the pathname above is correct; the given stylesheet has 
more lines, but I've pared it down to the above line by line, with 
each version giving the same core dump)

The following output is shown:

$ xsltproc --nonet simple.xsl simple.xml

Writing pr01.html for preface

Writing ch01.html for chapter

Writing ch02.html for chapter

Writing index.html for book

Writing htmlhelp.hhp

Aborted (core dumped)

When I run the command using verbose mode, I get the following just 
before the core dump:

===============================================

[...output truncated...]

xsltIf: test $htmlhelp.hhc.folders.instead.books != 0

Lookup variable htmlhelp.hhc.folders.instead.books

found variable htmlhelp.hhc.folders.instead.books

xsltIf: test evaluate to 1

xsltApplyOneTemplate: copy unescaped text <OBJECT type="text/site 
properties">

<param name="ImageType" value="Folder">

</OBJECT>

xsltCopyText: copy unescaped text <OBJECT type="text/site properties">

<param name="ImageType" value="Folder">

</OBJECT>

Aborted (core dumped)

===============================================

xsltproc -version shows the following:

$ xsltproc -version

Using libxml 20620, libxslt 10114-CVS1011 and libexslt 812-CVS1011 
xsltproc was compiled against libxml 20620, libxslt 10114 and libexslt 
812 libxslt 10114 was compiled against libxml 20620 libexslt 812 was 
compiled against libxml 20620

Am I doing something obviously wrong here? ANy help appreciated.
