When summoning a falling sand entity with the block id of redstone wire, the client crashes. Attached is the Crash Report.

As far as I'm aware, the FallingSand entity works fine with all other block types, even partial blocks like flowers and tall grass. Redstone wire only appears to crash the game because of a "tesselating block model", probably because the game is not sure how it's meant to be orientated.

The Commands used are:

/summon FallingSand ~ ~ ~ {TileID:55}

And

/summon FallingSand ~ ~ ~ {Block:"redstone_wire"}

They both cause the same crash.

Also summoning redstone wire worked fine in 1.7.*, albeit it had a glitched white "+" texture until it landed.
