Comment 6 for bug 365944

I can confirm this bug with the installer of Karmic Koala Beta, 64 bit, alternate cd.

These are my partition tables, they seem to be perfectly OK:
root@hardy64:~# fdisk -l /dev/sd?

====================

But the partitions on /dev/sda are not shown in the installer. If I press ENTER on sda, the installer wants to create a new partition table. Photo attached.

I'm going to change the title of this bug, since it won't get fixed for older version of Ubuntu anyway and it's relevant to the upcoming release.
