I'm not sure if it's really a bug. On 2.16.2 the same happens.
I guess that pageBreaks needs an object afterwards, otherwise it doesn't
make sense. You can use an empty \markup to work around the problem:

\version "2.18.0"

\layout {
  \override NonMusicalPaperColumn #'page-break-permission = ##f
}

music = \relative f' {
  e1 c c c c c c c c c c c c c c c c c c c c c
  c c c c c c c c c c c c c c c c c c c c c c f
}

\score { \music }
\score { \music }
\score { \music }
\score { \music }
\pageBreak

\score { \music }
\score { \music }
\score { \music }
\score { \music }
\pageBreak

\markup \null
