Not only some where placeable, it's any block

Same problem. Created new world in current snapshot - everything fine until placing a ladder.

Same thing happened to me. I was working on a mansion, and when I placed a ladder, Minecraft crashed! (I was using version 14w28a, by the way.)

Same thing happened to me today on 14w28a. Doesn't matter where I place a ladder, new ladders crash the game
