afterGrace is defined as

#(define-music-function (fraction main grace) ((scale?) ly:music? 
ly:music?) ...)

You write

\afterGrace 1 { s8 \clef "bass" } | c,1

but 1 is a valid scale? because of

(define-public (scale? x)
  (or (and (rational? x) (exact? x) (not (negative? x)))
      (fraction? x)
      (and (ly:moment? x) (scale? (ly:moment-main x)))))

in scm/c++.scm.
