[MC-9788] Mob Spawners failing to "Saving entity NBT"

When using a spawner that spawns multiple types of items the game seems to crash giving the following errors. I have managed to recreate this crash off of 4 different mob spawners 4 different times. All of witch worked in the previous snapshot 13w06a. When playing with 13w07a the game crashed but downgrading back to 13w06a allows the game to run perfectly fine. I have included a .schematic file that can be used to replicate the crash.

Actually THIS is a duplicate of MC-9778. Look at the date it was created "Yesterday 10:13 PM" this was created 1h and 27 mins later.

I'm having the same problem, but I'm not sure how to fix it, because I do want to spawn items using spawners. Is there a workaround for this?

It's not the items being bugged, but the spawners.

If you download that map ^^ (awesome map btw) you'll see the items get spawned normally but when you fly to close to the spawners the game will crash.

As of right now the only work around to my knowledge is to downgrade snapshots (witch isn't really a work around) or to just use spawners that don't spawn multiple entities
