After running into several other situations where one of these logout/lock screen dialogs got wedged and I had to reboot, and after losing all my work several times because the default ctrl-alt-del action is to log out rather than lock the screen as it has been in Windows forever, I just set ctrl-alt-del to lock the screen with no prompts or dialogs. So I guess you can close this though I still think this area of ubuntu is poorly implemented
