New issue 3263 by address@hidden: LyricText has wrong parent after  
switching voices
http://code.google.com/p/lilypond/issues/detail?id=3263

\version "2.17.12"

\markup \wordwrap {
  When lyrics switch alignment from one voice to another
  and then back to first voice, second syllable after
  the return switch ("\"huh\"" in example below) doesn't
  have its parent set correctly - instead of NoteHead,
  it reports that its parent is a PaperColumn. A visible
  effect is that the syllable is left-aligned instead
  of centered (this behaviour will probably change when
  issue 3254 is solved).
}
\score {
  <<
    \context Voice = first {
      e'2 e'
      \context Voice = second { d''2 d'' }
      d'2 d' d'
    }
    \context Lyrics = foo \lyricsto first \lyricmode {
      one one
      one huh one
    }
    \context Lyrics = foo \lyricsto second \lyricmode {
      two two
    }
  >>
}

\markup {
  The problem doesn't appear when lyrics
  are connected to notes using associatedVoice:
}
\score {
  <<
    \context Voice = first {
      e'2 e'
      \context Voice = second { d''2 d'' }
      d'2 d' d'
    }
    \context Lyrics = foo \lyricsto first \lyricmode {
      % associatedVoice must be set one syllable early
      one \set associatedVoice = "second" one
      two \set associatedVoice = "first" two
      one huh one
    }
  >>
}

\markup {
  Interestingly, the problem disappears
  when one syllable is deleted:
}
\score {
  <<
    \context Voice = first {
      e'2 e'
      \context Voice = second { d''2 d'' }
      d'2 d' d'
    }
    \context Lyrics = foo \lyricsto first \lyricmode {
      one one
      one huh one
    }
    \context Lyrics = foo \lyricsto second \lyricmode {
      two
    }
  >>
}
