OK, that means "the music view is gone" is not correct. It's that it
can't display anything. Which underlines the suspicion of the poppler
dependency issue.

This may well be true, but the traceback looks like this one:
https://github.com/frescobaldi/frescobaldi/wiki/Run-Frescobaldi-3-on-Linux#workaround-building-python-poppler-qt5-from-source
and
https://github.com/frescobaldi/frescobaldi/issues/838

I wonder if it's still possible today to have that problem with Linux
packages. What distribution/desktop do you use exactly?
