Crash involving rabbits

I was walking around my rabbit farm and all of a sudden i crashed. each time i try and load that world it just crashes now. i opened the world in an older snapshot and i was able to get on but all the rabbits were acting as if they were tamed wolfs and were teleporting to me.
Looking at the crash notes it seemed to be caused by the rabbits as it said
