1.77.0 bug with index building?

[Stefan Hinz <stefan.hinz@oracle.com>]

We're building customized XHTML output for OTN (Oracle Technology 
Network), for many books. Using the 1.76.1 style sheets, all works fine, 
but switching to the 1.77.0 style sheets gives an error like this:

XML_CATALOG_FILES="../../../mysqldoc-toolset//catalog.xml 
../../../mysqldoc-toolset/xsl.d/docbook-xsl-1.77.0/catalog.xml" xsltproc 
--xinclude --novalid  \
        --stringparam l10n.gentext.default.language en \
        --stringparam html.stylesheet "mysql-html.css" \
        --stringparam generate.toc "book toc,title" \
        --param chunk.section.depth 1 \
        --output user.xhtml-otn-tmp/ \
        ../../../mysqldoc-toolset/xsl.d/mysql-xhtml-otn.xsl \
        user-prepped.xml
../../../mysqldoc-toolset/tools/add-index-navlinks.pl 
user.xhtml-otn-tmp/*.html
Cannot find top of index 0, file user.xhtml-otn-tmp/ix01.html
make: *** [user.xhtml-otn] Fehler 25 (German for "error 25")

This is reproducible for all our books. It might not be a bug in the 
1.77.0 style sheets, but rather something in our customization layer 
that must be adapted to work with the new style sheets. However, I'm at 
a loss how to start debugging this.

Any pointers appreciated, and of course I can provide our customized 
xhtml-otn style sheet if necessary to track down the problem.
