I had just started a new game and I noticed that when I tried to break spawned chests in villages the game would just crash if I had never open those chests. The crash wouldn't happen if I had open the chests first as I noticed as well. So well, what I was expecting is to get the items inside the chest and the chest with no crashes at all.
Summarizing the steps to get the bug:
1. Find a chest you have never ever opened.
2. Break the chest.
3. Watch the game crash.
Thank you for your report!
