I'm re-installing ubuntu, instead of upgrading from 8.04 to 9.04. When I put in the Live CD and boot nautilus does not load. When I execute nautilus from the command line all I get is "Segmentation fault". I have no idea why this would be a problem in a live environment but this might explain how my 8.04 nautilus stopped working after an upgrade.
I've already run the built in self test on the CD and it checks out fine. Does anyone know why nautilus would fail in the live environment?
