Double doors used by villagers cause the game to crash upon being destroyed

The villagers immediately claimed blocks and went indoors to work, however they all showed odd behavior if the building they were in had a double door. As soon as they ended their "shift" in their workstations, all the villagers inside buildings with double doors proceeded to open just one door, leave it open, and then pace around it while still inside the building.

Closing the door caused them to open it again and repeat the faulty behavior. I assumed the problem was the block itself, and tried to replace the double doors with just a single door. However, upon destroying the door the villagers used, the game crashed.
