Well the today's daily image is busted due to bug 1053317 which has been fixed in 1.78ubuntu2 and uploaded as part of the installer in https://launchpad.net/ubuntu/+source/ubiquity/2.12.1
So I think you should either use beta1 image or wait for tomorrow's daily.
You can check jenkins auto tests first before trying daily ISO https://jenkins.qa.ubuntu.com/view/Quantal/view/ISO%20Testing%20Dashboard/
And you have the same symptons in you bug report as bug 1053317
