Fedora lilypond will not compile with large character set fonts

As of at least 2.19.19 onwards the 64 bit Linux binary download of lilypond
will not compile files on Fedora 21 if they use fonts with a large character
set, for example, the Linux Libertine fonts. The warnings issued by
ghostscript about embedding a subset of the fonts are treated by lilypond as
fatal errors.

This code will not compile:

% fedora-bug.ly

\version "2.19.19"

\paper
{
  #(define fonts
     (set-global-fonts
      #:roman "Linux Libertine O"
      #:sans "Linux Biolinum O"
      #:typewriter "Linux Libertine Mono O"
      #:factor (/ staff-height pt 20)
      ))
}

\relative c'' {
  c
}


Lilypond error message:

warning: `(gs -q -dSAFER -dDEVICEWIDTHPOINTS=595.28
-dDEVICEHEIGHTPOINTS=841.89 -dCompatibilityLevel=1.4 -dNOPAUSE -dBATCH
-r1200 -sDEVICE=pdfwrite -sOutputFile=./fedora-bug.pdf -c.setpdfwrite
-ffedora-bug.ps)' failed (256)

fatal error: failed files: "fedora-bug.ly"

Running ghostscript standalone:

$ gs -q -dSAFER -dDEVICEWIDTHPOINTS=595.28 -dDEVICEHEIGHTPOINTS=841.89
-dCompatibilityLevel=1.4 -dNOPAUSE -dBATCH -r1200 -sDEVICE=pdfwrite
-sOutputFile=./fedora-bug.pdf -c.setpdfwrite -ffedora-bug.ps
GPL Ghostscript 9.15: Can't embed the complete font LinLibertineO as it is
too large, embedding a subset.

The warning is issued but the output file is produced. Lilypond will not
produce the output file.

Building lilypond from source on Fedora 21 makes a version of lilypond that
does not show this error behaviour.
