Just try to leave out things. Try less notes (and less voices), less 
different pitches, less staff switches, only one example of failing 
\parenthesize; leave out unnecessary overrides and explicit script and 
stem directions, clefs, time signatures, and function definitions that 
aren’t necessary for the example …  And try to completely leave out the 
staff switch (but print a kneed beam on one staff) and you’ll find that 
it seems to be necessary to reproduce the error, so leave it in. Here is 
a much smaller example:

\version "2.19.25"

<<
  \new Staff = "upper" {
    s4
  }
  \new Staff {
    b16-\parenthesize-> b b
    \change Staff = upper
    b
  }

This seems to be a lilypond bug, so you’re not doing anything wrong. I 
reported it to the bug list.
