Since this bug reappeared on my system, this may help;
running gnome-power-manager --verbose
shows this line during the initialization:

 - No outputs have backlight property

Maybe the g-p-m just doesn't detect that the screen is lcd with backlight, and because of that it doesn't turn the backlight off?
Also I've noticed that after the initial display blanking by g-p-m, it will try to turn the monitor completely off every 10 minutes, which is the time out set in my g-p-m settings, and then after a split second the backlight turns on again.
