The only way I could get install to proceed without hanging was to:
a. Boot live session - selecting 'Try Ubuntu' option.
b. Open nautilus and mount a partition (happened to be /home)
c. Start install Ubuntu.

Previous workarounds did not seem to help e.g. CLI ubiquity --debug, starting gparted then closing.
I hope it gets fixed before release as having an OS not able to install from its media is not a great selling point for new users :-(
