Piston falling on Redstoneblock Crashes game

When You Summon a Falling Sand Entity
then set it to a piston with Data value 6

I used the datatag:

{Time:1,TileID:29,Data:6}

and make it land on a Redstone block will crash the game

I think the game doesn't know what to do when this piston gets updated.
