Comment 19 for bug 1747646

I moved the above bug to GVFS: https://gitlab.gnome.org/GNOME/gvfs/issues/360

In that bug, I've attached a Python script that reproduces the problem. So this is not unique to duplicity or deja-dup.

However, we might reasonably work around it in duplicity by remounting or similar when such an error occurs. Maybe in _retry_cleanup as Andrew suggests.
