[hardy] Long wait after keyboard layout selection during installation

I tried installing from the Hardy Heron Alpha2 live cd. All is ok but one thing will bite a lot of first time users.

After you press next on step 4 of 7 of the installer (the keyboard layout) a dialog appears showing the progression of the disk scanning. This goes to completion, disappears and then the system seems to hang. In my case it hangs for about 4 to 5 minutes without any indication of progression. On the first try I aborted. When you wait long enough you get through properly.

Since it's known when step 5 of 7 appears on screen it would be nice to have some indication that the system is not hanging after the scanning of the disks.
