I forget. See the attached Makefile (and replace the
defguide/en/Makefile with the attached one) to create bookinfo.xml with
xsltproc and you don't need any further stuff from upstreams SVN to
create all files to reproduce the bug. Just run

make bookinfo.xml
xml2po -e -o book.pot book.xml

to try to reproduce the bug.
