It ignores most tags of the item, not only the enchant.

I know. I didn't care about spelling, simply detonated a creeper.

I checked MobGriefing and it was set to true.

Commands used:
/summon Zombie ~ ~ ~ {CanPickUpLoot:1}
/entitydata @e[type=Zombie,r=40] {CanPickUpLoot:1}

Breaking water block causes this sound.

So, it should work only if player is riding.

Confirmed for 1.8

Name tag doesn't work on adult villagers, because they can't be renamed. You can name only babies.

Bug confirmed for 1.8

NoAI tag works only on mobs, not on minecarts and other non-mob entities.

Confirmed for 1.8

I spawned this minecart with spawner using summon command. It spawns mobs correctly, but mob miniature is incorrect (pig instead of skeleton). Effect of this bug is only visual, it does not affect spawning.

Bug affects all minecarts with spawner in 1.7.2. Tested with 5 types of mobs, always the same result (pig miniature inside the spawner).
