Quoting music in ly:book-process

[Mark Witmer]

I can't seem to get quotes/cues working in a score generated with ly:book-
process. This is my code:

% Quoted notes should appear in music created with ly:book-process,
% but they do not
\version "2.16.0"
myPaper = \paper {}
myLayout = \layout {}

\addQuote "test" {c1 b1 a1}

#(ly:book-process 
  (ly:make-book myPaper (make-module) 
   (ly:make-score #{ 
    \new Staff {
      {a1 \quoteDuring "test" {s1 s1} g1 }
  } #} )) myPaper myLayout "quote-test")

The two bars with spacer rests remain empty in the output. The problem is the 
same if I move the \addQuote statement to the inside of the \new Staff {} block.

Is there a way to work around this? It looks like a bug to me.

Thanks,

Mark Witmer
