Steps to reproduce:

• Place a firework generator
• Place a chest on the generator
• Configure the generator to auto-pull from the chest
• Take a firework from the creative inventory and put it in the chest
• Watch the game crash

After this the world also crashes when opening it.

The step with the chest is needed because you cannot just place the firework into the inventory by hand. I'm guessing there is a mismatch between the requirements for auto-pulling a stack and manually inserting it, though I haven't dug into the code too much.
