Right, I saw in some other bug report that it was no longer needed or
was a legacy configuration item. In that case, it should be dropped from
the default /etc/mpd.conf shipped in the package:

rak at zeta:/tmp$ ar p mpd_0.23.3-1_amd64.deb data.tar.xz | tar JOx ./etc/mpd.conf | grep pid_file
pid_file                        "/run/mpd/pid"

I can confirm that 0.23.3-2 fixes this bug and that I can run mpd with
the minimal mpd.conf, assuming that I delete the pid_file line. (With
the pid_file line, it runs into the issue you described in the rest of
your email:
