Item related crash in Nether after dying

*This actually happened on 1.0.0 yesterday before the update, but that is no longer an option from the dropdown*

After dying in the Nether (on a Realm) and going back to retrieve my items, opening the inventory caused the client to crash. After numerous times trying to retrieve the items and escape the nether, I tried picking my items up again and the game instantly crashed when a certain item was added to my hotbar. After successfully escaping the Nether and being able to open my inventory without crashing, I noticed that the clock was one of the only items I was missing. I was able to take the clock in with me no problem, but it seems the game crashed every time it tried to display the clock on screen after I died.
