I will try that but if true why doesn't xsltproc choke on the same image
when I create HTML?

Hello Steve!
The error you get is most likely caused by some erroneous PNG image file or
some other image file with alpha transparency. Ask Google for more information
about this issue. You need to find out which image file is causing the error.
The most common solution is to simply run that image file through ImageMagick.
See e.g.

In my customization file for FO processing, I have this:
<xsl:param name="admon.graphics" select="0"></xsl:param>
<xsl:param name="admon.graphics.path">Graphics/</xsl:param>
If I change the first line to:
<xsl:param name="admon.graphics" select="1"></xsl:param>
I get a horrendously long and ugly stack trace and I don't know why. Help?
(xsltproc handles it fine)
