I go to open a barrel to access its contents, then the game crashes. I then restart the game and load the world for it to instantly crash again. Upon another restart and world load, the game runs fine until I open the barrel again. I do not know if it's because I was creative mode, or if I had villagers nearby, or if I was using the Fullscreen mode. When I tried to recreate the bug in a new world, it would not reoccur except in the world where it showed up.
What I expected to happen was...:
I expected to place lovely loot in a barrel
What actually happened was...:
The barrel acted moody and crashed my game, and then again when I try to reload the world.
Steps to Reproduce:
As I am not sure what caused it to begin with, I cannot add any more than to attempt opening a barrel when there are three villagers nearby with a cauldron, and two composters. Maybe there was an error in villagers trying to decide what was theirs?

Confirmed in multiplayer 19w11a, if barrels are placed in 19w09a or earlier, opening them would crash the server. Rendering it again would also crash the server once more. New barrels work fine. Breaking broken barrels works fine too.
