[MC-45240] FallingSand spawner crash the game

I tried to update my FallingSand spawners, but even if I add

{block:"minecraft:stone"}

in the FallingSand tags, the game crashed when the Entity spawn.

Here's the command I'm using:

setblock ~ ~1 ~ minecraft:mob_spawner 0 replace {SpawnData:{Data:0,Dimension:0,DropItem:0,Motion:[0.0,0.06,0.0],Pos:[562.5,92.5,7.5],block:"minecraft:dirt",Time:0},id:MobSpawner,EntityId:FallingSand,SpawnCount:2,SpawnRange:5,Delay:1,MinSpawnDelay:0,MaxSpawnDelay:1,MaxNearbyEntities:64}

Works fine in 1.7. Using the TileID tag doesn't work too.
