A strange bug happens when I destroy a framing table and causes Minecraft to crash http://pastebin.com/3077W3Wz

I'm not sure if it's the particular way the table is being destroyed, or it's a multiplayer problem or just random. I've checked in a guard that should prevent a crash (though it's possible you still have a tile hanging out where the game thinks there's an air block). Will be available in the next releases for 1.8.9 and 1.9.4.

Should be fixed now in 1.8.9 and 1.9.4.
