there's an item that minecraft doesn't recognize in the chest, and it crashes because it doesn't recognize the item. It's a common thing with mods actually. If you use a mod, and leave the modded item in a chest, then return to playing vanilla minecraft, you can't open the chest with the modded items without crashing the game. Also if you break the chest, you crash the game.
On all seriousness.
I would believe if you get a game editor you could go into the chest using the program and remove that one mod item.
Or just delete the chest.
