I have this issue and wondering if it's related to not being able to open a world to LAN without it crashing. Ton of stuff like (cannot upload or screenshot as this log file is over 100 pages long!!!!:
The following messages are a sample of what's strewn throughout regarding blocks, items, etc...

Those go on forever and then a few entries like this:
[b#439] 2014-10-20 14:01:43 [sEVERE] [Minecraft-Client] ########## GL ERROR ##########
[b#439] 2014-10-20 14:01:43 [sEVERE] [Minecraft-Client] @ Post startup

It's happening on two different machines where we try to open particular worlds to a LAN (some worlds we can open and others we cannot cuz it crashes.
