Karol,

I've seen this kind of thing happen in other cases (but I can't remember a
single one at the moment). The issue is that you must \unset the
proportionalNotationDuration one note PRIOR to when it is to actually take
effect. Like this:

{
  \set Score.proportionalNotationDuration = #(ly:make-moment 1/32)
  \repeat unfold 31 { f'32 }  % notice the 31 instead of 32
  \newSpacingSection
  \unset Score.proportionalNotationDuration
  f'32  % here's the 32nd note, but the \unset doesn't effect it, just
starting with the notes...
  f'4 f'4 f'4 f'4
}

Not sure why this is the case, but I think there's a technical reason that
it must be this way (I wish I could remember other cases where this
applies... Any else remember other cases where this happens?).

Regards,
Abraham
