Hopper inventory stops existing / Hopper Turns into Furnace

Once, a Hopper connected to the top of a Furnace transformed into a Furnace while I was away. It had the side texture of a Furnace, but was facing the wall, so I couldn't tell exactly what it looked like.
When I right-clicked on the bugged Hopper, Minecraft crashed. It's still there after reopening Minecraft.
Somehow, MCEdit also draws it as a furnace. The tags for it being a Hopper have been deleted, although it is still recognized as one.
Breaking it also caused a crash, but did remove the Hopper.
Crash might be related to the hopper's Inventory not existing.
I'm fairly certain only completely breaking it causes a crash, couldn't test since hopper was broken in creative mode. Unable to replicate.

Please attach the crash report, otherwise this ticket is incomplete.

Attached. (Finally, something I post isn't a dupe!)

Please attach your world as a zip and provide the coordinates.

Coordinates of Hopper:x=280, y=72, z=298

I'm sorry if my house gives you cancer

Just a note to find similar crashes 🙂

It means nothing unless you program Minecraft. This is just to make searching for tickets by their crash easier.

Is this still a concern in the current Minecraft version? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.

No reponse in a few weeks. Assuming the issue is no longer valid.
