Title:
  daily image launched from usb has partman crash

Status in “parted” package in Ubuntu:
  Confirmed
Status in “parted” source package in Trusty:
  Confirmed

Bug description:
  I've got the daily kubuntu amd64 desktop image on a usb stick, booted
  via grub2.  When I get to the part where the installer wants to
  unmount partitions, I get an unreadable error message, and the
  installer sits on "Preparing to install Kubuntu" with the Back and
  Continue buttons greyed out.
