I am also getting this bug intermittently on a fully patched Ubuntu 12.04. Just change the status to new. The released fix apparently never worked.

Lock your screen -> Confirm that the whole screen goes black [Regression Potential] Visual regressions, shell drawing problems. Part of a big change, many regression potentials. Original description: When I lock my screen, instead of the monitor going, black, the desktop background goes black, but the Unity launcher and the main bar stay visible. When I press a key or move my mouse the "unlock" dialog, asking me for my password pops up, centered on the black desktop background. I think the main issue here is gnome-screensaver failing to fullscreen.
