I made changes with sudo visudo on Ubuntu 10.04. I get error in shell:

sudo: unknown defaults entry `env_resets'

Try selecting the "Root Shell" item in the main menu -- AFAIK it is not dependent from sudo -- and edit /etc/sudoers with nano or your other favourite editor. The env_resets token should have been typed env_reset.
