[MC-414] Light glitch on corner stairs and slabs

Black shadow appears when creating upside down corner stairs or half slabs (see images).
Bug appears with Smooth Lighting ON and OFF.

Edit:
26-Oct-12: I just found out why the bug is happening. If I remove the blocks behind both stairs the glitch goes away. I added pictures 2-3-4

Does this still happen with Smooth Lighting turned off?
Could be an AO bug.

It does happen with Smooth Lighting turned off. It is actually worst because the shadow goes completely Black.

Same happens with 2 upside down stairs on the ceiling with a block free between them, it is totally black until you remove the block above (between the 2 stairs).

MC-626 mentions this also affects inverted slabs.
