I am experiencing this on Hardy as well. After resuming from hibernate, especially if I've connected to another network in the meantime, I enter my login password once to unlock the screen, then nm-applet asks for it again in order to unlock the keyring and supply my WPA key. I do not believe this is a dupe of 157511, since that is referring to the WPA key, NOT the login password. They are different issues.
