x-nautilus-desktop: shouldn't be leaking out of nautilus, as its an
internal-only thing. We probably need to plug that at some place we've
missed.

Wrt to uris pointing to the selected icon or the file that points to,
this is a problematic issue. In some cases you really want to
distinguish the volume icon from the path where its mounted, so we can't
really always pass the activation uri. (For instance, then you couldn't
ever copy a desktop file link, as you'd be copying what it points too.)

However, if you just want to open the location it points to, just look
at the URL key in the file (its a desktop file). Also, it has a
X-Gnome-Volume key that you can read and look up the GnomeVFSVolume with
gnome_vfs_volume_monitor_get_volume_by_id().
