Subject: Ugly stack trace with admon.graphics and FO
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)
