Problem with "HaraKiri"

[Mats Bengtsson]

The following example illustrates a problem with 1.1.29,
(I guess it's not the most common construct but it happened to me).
What the problem is? - Try to run it and see what TeX says.

---------------------
m=\notes\relative c''{

c1 | \break
R1*5 |
r2 r4 \bar "||"; \break r |
c2 c |
}

\score{
  \type StaffGroup <
      \type Staff = staffi {\m}
      \type Staff = staffii {\m}
    >
}
------------------------
