problem translating documentation in lilypond/translation

[Till Rettig]

Hello,
I get this error when making web on lilypond/translation branch:

./introduction.texi:1099: pdfTeX error (ext4): \pdfendlink ended up in

t nesting level than \pdfstartlink.

./introduction.texi:1099:  ==> Fatal error occurred, no output PDF file

Transcript written on lilypond-learning.log.
/usr/local/bin/texi2dvi: pdfetex exited with bad status, quitting.
make[3]: *** [out-www/lilypond-learning.pdf] Error 1

I didn't spend too much time investigating, the file introduction.texi 
has only 977 lines, where is the mistake located? Is it fixed in GDP?

Greetings
