Thanks for taking the time to report this bug and helping to make Ubuntu better.
The default root password does not exist (rather than being "empty"). You can verify this with:
sudo grep root /etc/shadow
It should report a line starting with:
root:!:....
The "!" means the password is locked. With a default Feisty install, I am not able to log in as root as you've described. Have you made any changes to root's password or your PAM configurations?
