psfonts problem with lilypond-book - strange behaviour?

[Dominic Neumann]

address@hidden,

I´m working with lilypond-book and LaTeX to typeset a songbook. Since
today there´s a problem with the PDF creation.

Here´s a short example:

%%% TEX FILE songbook.lytex %%%

\documentclass{book}

\begin{document}

\lilypondfile{herr_erbarme_dich.ly}

\end{document}

%%% END OF TEX FILE %%%


%%% INPUT FILE herr_erbarme_dich.ly %%%

\version "2.10.20"


\header {
        title = "Herr, erbarme dich"
        tagline = ##f
        %composer = "T. u. M.: Fritz Müller"
}

\score {
       <<
       \relative c' {
           \key e \minor
           \time 4/4

           e2 fis
           g4 g8 fis8~ fis2

           \bar "|."
       }
       \addlyrics { Herr, er -- bar -- me dich, __ }
       >>
}
%%% END OF LILYPOND INPUT FILE %%%


The clue is that files that worked only yesterday don´t today. I
already reinstalled lilypond (2.10.20 on WinXP) but nothing changed.

When I comment the line
    title = "Herr, erbarme dich"
out, the compilation produces no errors.

I used the proposed workflow:

lilypond-book --psfonts songbook.lytex
latex songbook.tex
dvips -o -h songbook.psfonts -Ppdf songbook.dvi
ps2pdf songbook.ps

The output of the last command (ps2pdf) is:

This error description didn´t lead me to a solution to the problem ...

Can anybody help me?
