This bug was fixed in the package ubiquity - 2.5.27

---------------
ubiquity (2.5.27) natty; urgency=low

  * Drop code related to debian-installer/fallbacklocale, since that
    template no longer exists (LP: #736060).
  * Update imported translations from gtk+2.0 2.24.3-0ubuntu2 and
    gnome-panel 1:2.32.1-0ubuntu6.
  * Ensure that PartedServer dialogs are always properly closed on
    exceptional paths.
  * Fix partition-table-full check to cope with disks without a partition
    table.

Today's amd64 build of natty is not updated, but I confirm the 2.5.27 working in the customized amd64 image
