footnote.xsl line 94 Failed to compile predicate

[Alan Ezust <alan.ezust@gmail.com>]

I'm getting a strange error message while trying to run xsltproc on the fo stylesheets. It caused a segfault in xsltproc!

xsltproc --stringparam ulink.footnotes 1 ../docs/printstyle.xsl index.docbook
xsl:attribute-set : use-attribute-sets recursion detected
Making portrait pages on USletter paper (8.5inx11in)
XPath error : Undefined variable
$ulink.footnotes != 0
                 ^
error: file ../docbook-xsl/fo/footnote.xsl line 94 element number
Failed to compile predicate
Segmentation fault

The offending line is this:
     <xsl:variable name="fnum">
        <!-- FIXME: list in @from is probably not complete -->
        <xsl:number level="any"
                   
from="chapter|appendix|preface|article|refentry|bibliography"
                   
count="footnote[not(@label)][not(ancestor::tgroup)]|ulink[$ulink.footnote\
s != 0][node()][@url != .][not(ancestor::footnote)]"
                   
format="1"/>
      </xsl:variable>

Any clues as to what is wrong here?
