I also am experiencing this bug with an encrypted Lucid desktop with an ATI Radeon HD 2400. It happens invariably when logged out and occasionally when logged in. If you run "sudo killall Xorg" to restore X, then you will get a new GNOME session but switching to a virtual console will then invariably crash.
