[xml/sgml-pkgs] Bug#683163: xmlto fail to convert example docbook to PDF (LaTeX Error, missing \item?)

[Petter Reinholdtsen]

Package: xmlto
Version: 0.0.23-2

I ran into a problem with the PDF suport in xmlto.  I see the problem
with a larger file (the freeculture.xml file available from
<URL: https://github.com/petterreinholdtsen/free-culture-lessig >, but
was also able to see it with an example file available from
<URL: https://trac.v2.nl/export/7884/v2fo/trunk/v2fo/lib/docbook/test/book.xml >.

I changed the XML slightly like this to get it to verify with xmllint:

Any idea what is wrong?

Attaching the example file, to ensure it is available for future
reference.
