Put the summary of the bug you're having here

What I expected to happen was...:
The minecart would pop and the item would drop like any other when the minecart hits a cactus/lava/fire (when it gets damaged)

What actually happened was...:
The game crashed

Steps to Reproduce:
1. Build a minetrack with cactus/fire/lava at the end
2. Put a minecart on the track
3. Give the minecart a push to make it move.
4. Let it run into the cactus/lava/fire

P.s im using the Nexus 7 (2013 model 16 GB) on android 4.4 in case that matters.
