  == Original 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.
