In installation, gui falsely claims there are no other users/OSs that can be imported

[Christopher Barrington-Leigh]

I installed 11.04 in a partition next to 11.04. I set /home to the existing /home partition. Yet the install process for 11.04 (all disks ext4) claimed there were no users to import. This keeps happening. What a pain to always have to recreate a second superuser, then transfer over / delete /or etc it later.
 Correct behaviour would be to find the user or not claim it had tried if it doesn't know how. It surely couldn't get easier than finding a linux user already on the /home partition, with /etc/passwd stuff on a same-distro linux partition?
