Bug description:
  I was testing this iso: http://cdimage.ubuntu.com/daily-live/20120925/quantal-desktop-armhf+omap4.img installing from a SD card to a USB key.
  In the "Installation type window" I selected "something else" and tried to modify the USB key partioning.
  On this USB key I had a prevoius installation of Ubuntu Beta2, I tried to cancel /dev/sda2 and enlarge /dev/sda1, but the installer got blocked and even if I waited for a long time it kept on having the cursor blinking with a circle and never stopped.
  I had to reboot from command line.
  I'm attaching a screenshot.
