      The bug

      Summoning a stack of mobs with a mob on bottom, an item frame in the middle, and a mob on top - a bee for example - will crash the game when the item frame breaks.

      How to reproduce

      1. Use this command:
        /summon wolf ~ ~ ~ {Passengers:[{id:"item_frame",Passengers:[{id:"bee"}]}]}
      2. Wait for the item frame to break
        Game crashes
