Does this occur with the 2.19.19 build in updates-testing?

yes. Lilypond is still not usable on F22 :-( 

If I run: 

lilypond foo.ly

the output is:

Warning: '(gs -g -dSAFER -dDEVICEWIDTHPOINT=595.28 -dDEVICEHEIGHTPOINT=841,89 -dCompatibilityLevel=1.4 -dNOPAUSE -dBATH -r1200 -sDEVICE=pdfwrite -sOutputFile=./foo.pdf -c.setpdfwrite --ffoo.ps)' failed

And the resulting foo.pdf shows an empty page when viewed with gs or evince.

the file foo.ly can be any lilypond file but I tested with the following content:

\version "2.19.19"
\score {
  \new Staff {
    { c'4 d' e' f' }
  }
  \layout {}
}

I don't know if it is a bug that should be fixed upstream in LilyPond or Ghostscript or somewhere inbetween?

Since this works perfectly with 2.19.19 on f21 with ghostscript 9.15, it's a ghostscript issue.

Not necessarily: Apparently something has changed between GS 9.15 and 9.16 that upsets LilyPond. That doesn't tell what needs fixing: GS or LP.
But it surely needs fixing.

Lilypond user on lilypond mailing list suspects pango:

Thank you for your files.

I suspect an issue of pango package of fedora 22.

First, I've tried your f22test.ps on my environment with gs-9.15.
It is failed. That is, it is not gs-9.16's issue.
The result is following.

```
$ ps2pdf14 f22test.ps f22test.pdf

```

Then, I've found problems of f22test.ps.
Broken f22test.ps sets font size to zero.
Using the patch file for f22test.ps that is attached to this mail,
ps2pdf14 is succeed.

If I understand correctly, LilyPond gets the font size from pango.
www.lilypond.org version LilyPond bundles pango that has no problem,
and always uses it.

Tried updating ghostscript locally to latest git, no help.  There is a new release of pango, trying that locally.  If it works I'll build and push for rawhide and f22.

Updated pango doesn't help either.

From a user:

lilypond: /home/gub/NewGub/gub/target/linux-64/src/lilypond-git.sv.gnu.org--lilypond.git-release-unstable/flower/include/interval.hh:226: T Interval_t<T>::center() const [with T = double]: Assertion `!is_empty ()' failed.

Occurs only on lilypond 2.19.21 and up.

Fixed by fontconfig fontconfig-2.11.94-1.fc22.
