this is a very late response, i know, but i have been able to reproduce it lately (on a clean, new feisty)
so what did i do and how did i do it?
firstly i created a shortcut to the gnome-terminal
then i shut my computer down.
after this i rememberd i still needed to do something and therefore i started it again. ~5 seconds after i logged in i started the gnome-terminal. there i performed a sudo command and I was not asked for a password.
my theory about this is now: because i just logged in, feisty assumed that it is highly unlikely that someone else but me performes the command and therefore countes the login as authentification for sudo as well.
