Yes, I can see that it must be the new unity-greeter screen-locker that is blocking the screen power-down. As minnigaliev-r says, if you lock the screen with ctrl-alt-L or super-L, the screen locks but never powers off, but as soon as you enter your password to unlock it the screen powers off and then immediately powers back on again (so it looks briefly like the computer has crashed). But if you let the screen power off with a timeout and then lock itself automatically, it does actually power off.
