crysman, starting with Ubuntu 13.10 the power button is managed by systemd/logind (default action is to shutdown the system, see /etc/systemd/logind.conf). As of now xfce4-power-manager is not able to inhibit these actions (bug 1222021) and the function to popup a dialog and ask the user might be still broken.
