The Game crashes if you hold a carrot on a stick in the detection range of a pig that has a minecart chest on its back

I tout haveing a pig that has a minecart with chest on it woud make up for a cool way to transfer Items. What I had in mind is use a carrot on a stick to lore the pigs to me. But what happended was when I highliighted carrot on a stick in my hotbar the game crashed. It woud crash everytime I enter that world. Had to use NBTExplorer to delete my inventory so I can enter the world
