I build a minimum image of xfce for raspberry pi4 - 64 bit.
With the latest versions of the gvfs 1.42 package (1.42.1 or 1.42.2) of the master branch, on the desktop, mount and see other folders: pts, proc, run ... See attached image.

If I replace the gvfs package with the version of zeus branch 1.41.2, the desktop is fixed.
