guided partitoning for entire disk creates empty partitions

I was unable to recreate this using an Oneiric amd64 desktop CD from today - 2011-10-03.

I know its a hassle but could you possibly try testing this again with a later CD image?

No worries. I tried with the image http://cdimage.ubuntu.com/kubuntu/daily-live/current/oneiric-desktop-i386.iso synchronized with zsync Tue Oct 4 20:40:01 CST 2011

To be sure, I also create a completely new disk for this test. Interestingly, the installer crashed when it was almost done, but I have not had any opportunity to investigate that further. However, I figured the disks had already been partitioned, so I started a live session and ran sfdisk. The result is listed below (Note I installed on /dev/sdb, the second drive):

I also attach the definition file for the virtual machine, in case it helps.

ubuntu@ubuntu:~$ sudo sfdisk -l

I also just tried with the 64bit version that I downloaded Monday. This time the installation completed with no problems, but the partitions are still the same (I again created a completely new /dev/sdb/ that I used for installation)
