--- Comment #10 from Ken Sharp imwellcushtymelike@gmail.com --- Please try again in Wine 5.6 or later.
I know of some native Linux apps (VLC for example) that can also have problems with certain GVFS mounts. I have to workaround these by using 'sudo mount...'. I don't know if this is an option for you.
