What I expected to happen was:
For wooden doors to be removed from villages recognized from villagers.
What actually happened was:
Whilst removing wooden doors from a village the client/server will crash because the game cannot tick the villagers nearby.
How you reproduce this:
If the villagers do not recognize your wooden doors as a village no crash will occur, please make sure when confirming that you wait for villagers to recognize the village and you try multiple times if the crash does not occur.
Create a valid chamber that villagers will recognize wooden doors as a village.
Place a row of villagers in said chamber.
Wait at least 6 seconds for the villagers to recognized said village.
Start removing the doors.
Crash report attached.

I have the same issue. My village has a house where all the villagers congregate, so I was going to break the doors to make them spread out, and it crashed when breaking one of the doors.
Crash report: http://pastie.org/9382408
This is exactly what one of our players was doing. After placing several doors it was decided some were unnecessary. Whilst removing doors to a village the server crashed!
Confirmed for 14w29a
