Ubuntu 12.04 install freezes at completion of "Who are you?"

[Mark Emberson]

Your name, Your computer's name, Pick a username, and Confirm your password all have green ticks. The Installer doesnt hang until you press the "continue" button. Waiting for the progress bar along the bottom to complete before pressing continue also results in a freeze.
