I changed that to verification-done based on testing Ubuntu 12.04.2 LTS "Precise Pangolin" - Release i386 (20121130) which I grabbed from the QA tracker. If other flavors or architectures require testing please change that back to verification-needed with a list of flavors and/or architectures that require testing.
That image does now default to selecting /dev/sda which is certainly more appropriate and less likely to place grub on an external device.
