I believe this is a problem with cross-staff unbeamed tuplets.  Change the
final e,4 to e,8 e and all works well.  But if we add \autoBeamOff, the
same behavior is observed.

\version "2.19.39"

\paper {
     ragged-right = ##t
     ragged-bottom = ##t
}

rondoPiSU = \relative c'' {
     \time 2/4
     \autoBeamOff

     % c2 |
     \change Staff = ST f,4( \tuplet 3/2 { e8) \change Staff = SU e,8 e }
| %599
}


\score {
     \new PianoStaff = PI <<
         \new Staff = ST {
             \rondoPiSU
             \break
             \rondoPiSU
             \pageBreak
             \rondoPiSU
             \break
             \rondoPiSU
         }
         \new Staff = SU {
             \clef bass
             s2*4 |
         }
     >>
}


Thus,  I would make sure the issue title includes "cross-staff unbeamed
tuplets".


Thanks,
