Comment 75 for bug 946663

Unfortunately, we were not able to resolve this issue in time for the release. Even when simulating some of the disk layouts attached, I don't see the problem.

However, to help us track down the cause it would be extremely useful if someone would list the *exact* steps they take to see this problem: every button click and action performed.

If you are seeing this issue when installing via a VM, a screencast would be the easiest way to generate this information (xvidcap is great for this and simple to use - just drag the red rectangle over your VM window and hit 'record': https://wiki.ubuntu.com/ScreenCasts/XVidCap).
