John has kindly pointed out an Ubuntu Bug report where it sounds like someone is suffering the same problem with 2 headless servers.
From the Bug report: "I can only reproduce the problem on servers (with sshd, apache2, mysql, ... no dbus). On desktop installations the restart command works fine. I first saw the problem on lucid but it still occurs on maverick."
