You only get volume-pre-unmount when unmounting via gnome-vfs. And
unfortunately, everything in the desktop now unmounts via gio, so you
need to use that to get this.

GVfs has no bindings, because it doesn't have an API, its purely an
extension of glib. All the API is in gio (in glib), which is availible
at least in the python bindings.
