OpenSUSE :: PackageKit Authentication Fails Without Asking?

The first time PackageKit Update Applet ran, it asked me for the root passwordI accidentally pressed enter after making a typo, and ever since then Update Appletfails rror:Authorization failedYou have failed to provide correct authentication.Please check any passwords or account settings.Failed to obtain authentication. It never lets me input a new password. Two questions:1) Am I doing something wrong, or is this actually a bug? The possibility has been mentioned in other posts on the topic.2) Where does PackageKit store its files? I'll either change the password myself or delete the file where it's written, hopefully that will trigger PackageKit to ask again.
