Comment #2 on issue 2392 by address@hidden: Segfault in connection with \applyContext
http://code.google.com/p/lilypond/issues/detail?id=2392

Aaaand here is an even worse one:
\score
{
  {
    \skip 1
    \new Staff { c'1 }
  }
  \midi {}
}

All of those are pretty clearly caused by lily/score-performer.cc where the listener for OneTimeStep is called _before_ the listener for Prepare. Indeed, it would appear that Prepare is _never_ called at all. It's just that midi reacts more allergic to this than paper.

So the solution obviously should not be to make OneTimeStep robust against being called without Prepare but rather to fix the iteration logic so that Prepare _does_ get called.

I'm out of my depth with that one, so Cc to the masters.
