Rabbit Crashing (possibly by taming baby or adult)

I was playing the minecraft snapshot and tried to tame a bunny, after multiple attempts I tamed him(he had the default skin) so I tied him to a fence post and named him "Ox's Friend" then I proceeded to kill the rest of the bunnies I failed with. Then I clicked him with a spawn egg to make a baby one. I tamed the baby one(which oddly gave me green particles instead of hearts) tied him to a fence post and named him "Ox's littler friend". Then I walked around for a little while(nothing important). I then went to make a fenced-in area with a prismarine floor and a mossy cobblestone ceiling. When I finished the area I found myself in the area where I tamed the first bunny, and my game not responding. I turned off the game and I got this crash report:
