Title:
  ubiquity crashed with TypeError in function(): Argument 1 does not
  allow None as a value

Status in ubiquity package in Ubuntu:
  Incomplete

Bug description:
  Hallo
  Testing Ubuntu Desktop amd64 20130325 on an intel based pc.
  Loading ubiquity-dm waste a lot of time, all seems slow, but once the session is loaded seems to run ok.
  This usb key was already used for one installation on another pc, so probably there are something logged before this install.
  At the page Install I tried to click on Erase Ubuntu Raring Ringtail and reinstall, but the window was unresponsive, then apport popup the crash.
  Thanks
  Fabio
