Comment #7 on issue 3101 by address@hidden: Patch: Eliminates the  
Hara_kiri_engraver.
http://code.google.com/p/lilypond/issues/detail?id=3101

The patch looked fine.  It should prevent the segfault, and also let this  
input work as one would reasonably expect:

\paper {#(set-paper-size "a8")}
\new StaffGroup \with {
    \RemoveEmptyStaves
}  << { \repeat unfold 20 b1 }
      { \repeat unfold 10 R1
          %% \override VerticalAxisGroup #'remove-empty = ##f
          %% \neverEmpty
          \repeat unfold 10 R1 } >>

My comment was merely explaining that the override in the comment above  
will not change the 'frenching' of empty staves mid-score.  We will still  
need to define something like :
 neverEmpty = \set Staff.keepAliveInterfaces =
  #'(multi-measure-interface rhythmic-grob-interface lyric-interface
    percent-repeat-item-interface percent-repeat-interface  
stanza-number-interface)
