Hi David,

the problem:
in 2.18. the grob-parent of LyricText was NoteHead for both Voice and NullVoice.

In 2.19.37 it's NoteColumn in Voice and PaperColumn in NullVoice.
More, 2.19.37 returns for the LSR-code:
programming error: cyclic dependency: calculation-in-progress
encountered for #'X-extent (PaperColumn)
(with a buid from master with --enable-checking)

Right now I'm not sure how to deal with it (and when I'll have the
time to take a deeper look)


So far, cheers,
  Harm
