[Sab] core dump with 0.52

[dsh]

I get the following error with 0.52, but it works fine in 0.50.

sabcmd: expr.cpp:1435: const class Str &
Expression::tostringRef() const: Assertion `(functor == EXF_ATOM) && (type
== EX_STRING)' failed.
Aborted (core dumped)

Here's my xml and xsl

<?xml version="1.0"?>
<stuff>
        <tablewidth>500</tablewidth>
</stuff>

<?xml version="1.0"?>
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; version="1.0">
<xsl:output method="html" encoding="ISO-8859-1" media-type="text/html"/>
<xsl:template match="stuff">
<table border="0" cellspacing="0" cellpadding="0">
        <xsl:attribute name="width">
                <xsl:value-of select="tablewidth - 10"/>
        </xsl:attribute>
</table>
</xsl:template>
</xsl:stylesheet>

It's Linux 2.2.17 i686.  Everything else seems to be working fine.  Am I
using an incorrect syntax?

Thanks for your help,
Scott
