clip-regions

[Damian leGassick]

hi

if i use the example from 3.1.4 in my layout block:

 clip-regions

  = #(list

      (cons

       (make-rhythmic-location 5 1 2)

       (make-rhythmic-location 7 3 4)))

i get the following error with -dclip-systems:

Converting to `fugue-from-5.1.2-to-7.3.4-clip.pdf'.../Applications/LilyPond.app/Contents/Resources/share/lilypond/current/scm/framework-ps.scm:627:60: In procedure car in _expression_ (car systems):
/Applications/LilyPond.app/Contents/Resources/share/lilypond/current/scm/framework-ps.scm:627:60: Wrong type (expecting pair): ()

any clues?
