Bug description:
  I use Ubuntu12.10 Qantal daily build amd64 from 22.7.2012.

  This occures on a installation try from a usb stick.

  To be exactly on clicking the abort button on the Install Type
  dialog(Whole disk, paritioning...).

  This is the first time that I observe this on this daily build(some
  runs this day).

  So, I have no reliable reproducing procedure.
