Thanks, I managed to patch out too many things, now I understand better.
Fixed patch for Andreas (maybe):

I now just get red text that says "INVALID! try Score->Check Score
command...", I did so and it said no problem, but console spits out some
pretty weird error messages stating that "Denemo - WARNING : Trying to
read the pdf file file:///tmp/Denemo_FZSBD3/denemoprintA.pdf gave an
error: File type PDF document (application/pdf) is not supported".
Checked the file in /tmp, it's valid PDF as far as I (and Zathura) can
see, so Lilypond rendering is probably fine. Have you seen this before?
(This is not new at all, the same as when I've given up on fixing Denemo
on my machine the first time a few months ago, so probably not a recent
commit, might have even been just a broken dependency update.)
