The quick fix: s/2.19.41/2.18.2/
ie run "stable" LilyPond.

The new fix (AFAICT):

\layout {
  \context {
    \Staff
    \override StaffSymbol.break-align-symbols = #'(time-signature key-signature 
staff-bar break-alignment)
  }
}

The "explanation":

I haven't tried it on the tiny number of my scores that have ossias.
