Hi,

David Nalesnik's function correcting tuplet number placement on kneed
beams throws an error with Lilypond 2.17.5 (it works with 2.16.0):

Drawing systems.../home/janek/desk/tuplet_numers_on_kneed_beams.ily:44:26:
In procedure * in expression (* 0.5 (ly:grob-property beam #)):
/home/janek/desk/tuplet_numers_on_kneed_beams.ily:44:26: Wrong type: ()

line 44 reads:
(beam-gap (* 0.5 (ly:grob-property beam 'gap)))

i have no idea why this doesn't work.  I had looked for commits that
said something about gaps, but hadn't find anything.  Maybe it's
related to some commits about grob-properties:
