IF the gio copy command has the same issue then yes it's probably gvfs rather than nautilus to blame, you should report your finding on https://gitlab.gnome.org/GNOME/gvfs since that's the right place for upstream code issues (the Ubuntu team does integration and contribute in those projects but on launchpad you then only hit a subset of the people who can help getting it resolved)
