I have duplicated this in 1.7.2 and 1.6.4 superflat worlds by creating large stone structures with roofs made of redstone lamps.
Note: All the fake light sources exist along the chunk boundaries.
{X and Z coordinates c: (0, 15)}
This light source is equivalent to the light level at that location when the lamps were on. many of these fake light sources were several blocks away from the structures.
Ok, despite that fact that these fake light sources can fool me visually and even show up on the debug screen, they don't fool the zombies. I enclosed one of these apparently well lit areas with stone and dropped a zombie spawner on the ground. With the debug screen showing the lowest light level in the room as bl:9, zombies spawned as if the room were dark.... The zombies seem to be getting smarter.

I duplicated this a bit ago, missed arrows still there more than 30 minutes after 200 skeletons killed each other off. (1.7.2)
It's still present in 1.7.2 (I did search first, but didn't find this)

Uploaded my test world for the light bug. zipped using 7zip.
Still present in 1.7.4 pre-release
This bug as well as the darkness bug (dark areas that are well lit with torches etc) both seem to follow chunk boundaries.
Still present in 1.7.4 pre-release
Breaking the block the arrows are stuck in and allowing them to fall to the next block allows them to despawn in my 1.7.2 single player game.
