You are right. For now, as a workaround for this very annoying bug, installing XScreensaver will do the needful as explained on: https://bugs.launchpad.net/ubuntu/+source/xfce4-power-manager/+bug/1193716/comments/15
But, as you all may know, 'xscreensaver' is not installed by default with Lubuntu 13.10 :)
Hopefully this bug will be solved soon ;)
