Crash upon placing Crafting Table

Recording of this crash can be seen here: https://youtu.be/nPw2F2mWDfY?t=306
This happened consistently every time a crafting table was placed.

I am experiencing the same problem on 15w49a.

Here is my crash report.

Edit: I do not experience this problem on 15w47c

I also experience this crash if I open a world created in 15w47c and try to place a chest I crafted, or even just an oak wood log that I just harvested with my hand. I stopped testing blocks after these two.

Same Issue. Does not matter if it is a previously created world or newly generated in version 15w49a. Did not have this issue 15w47c. Crash log attached.
