Still trying to debug the issue. Reading this thread: https://bugzilla.novell.com/show_bug.cgi?id=638924
made me think that the "Unregistered Authentication" error that I get might be due to X crashing. So I played the same game with looking at the log at every step, but this time I focused on the Xorg log. When the gnome shell crashes, this is what I see: 341a342,350 > [ 312.083] (II) NVIDIA(0): Setting mode "DFP-0:nvidia-auto-select" > [ 312.138] (II) NVIDIA(0): ACPI: failed to connect to the ACPI event > daemon; the daemon > [ 312.138] (II) NVIDIA(0): may not be running or the "AcpidSocketPath" X > [ 312.138] (II) NVIDIA(0): configuration option may not be set > correctly.

I will continue debugging and keep you updated....
