Uni-directional pistons crashes game when updated

With some map editing one can create pistons that visually feature their front texture on all 6 sides. If a block update is applied to this block, the game will crash. The enclosed crash report resulted from placing a Redstone block next to the piston. While placing and removing an iron block (as a generic example I chose) next to it crashed the game, removing the Redstone block didn't have any effect.
