    Installed: 21.04.13
    Candidate: 21.04.13
    Version table:
   *** 21.04.13 500
          500 http://archive.ubuntu.com/ubuntu hirsute/main amd64 Packages
          100 /var/lib/dpkg/status

  KVM/Qemu 2GiB mem, e1000, IDE CD ROM, 16GiB (or less) IDE virtual
  Disk.

  * Behaviour 
  IDE qcow2 virtual disk image 16GiB selected.  CD ROM image boots, Desktop is displayed.  Dialog appears - "Installation failed -- LKialog ? - The installer encountered an unrecoverable error...".

  Repeated test on 12GiB disk - Same Error.
  Repeated test on 20GiB disk - Success, ubiquity loads correctly.

  * Expected behaviour
  Kubuntu Ubiquity continues to load with "Install Kubuntu" button. A warning to user during partitioning of insufficient disk space for Kubuntu install.   

  No /var/log/partman log present.
