Gnome Screensaver Missing Lock Screen Prompt in Ubuntu Lucid 10.04

For some reason, the unlock dialog box for Gnome Screensaver suddenly stopped appearing. Screensaver works fine but, move the mouse and no unlock prompt, just back to the screen saver. The only work-around was to press Ctrl-Alt-F1, login, and type the command:

killall gnome-screensaver
Although, after a while this gets annoying so, I looked for a better long term solution. Here it is:
sudo chmod a+r /etc/pam.d/*
That's it. I assume that the permissions may have been messed up during an update. Posted here for posterity.
