Does this still occur?

Yes, it does; but it has an indirect hard dependency on those schemas,
so they should really be installed already.

gvfs-daemons
    -> Depends: gvfs-libs
         -> Depends: gsettings-desktop-schemas

I tried installing gvfs-daemons with only its required dependencies
(without Recommends) on a test system, and was unable to reproduce this
bug. gvfs-udisks2-volume-monitor.service starts successfully.

Does /usr/share/glib-2.0/schemas/gschemas.compiled exist?

If it does, please copy it to
/usr/share/glib-2.0/schemas/gschemas.compiled.old for later analysis,
then try reinstalling the gsettings-desktop-schemas package with:

    apt install --reinstall gsettings-desktop-schemas

and send the output to this bug address.

Thanks,
