New issue 1428 by n.puttock: \book cannot contain \bookpart identifier
http://code.google.com/p/lilypond/issues/detail?id=1428

Placing a \bookpart identifier inside \book causes a segfault:

\version "2.13.41"

mypart = \bookpart {
  \relative c' {
    c1
  }
}

\book {
  \mypart
}

Program received signal SIGSEGV, Segmentation fault.
