Some more information now that I've done more testing on when I get the error. I get this near a squid farm I build. It's basically a water source placed over a half slab that cascades down about 20 blocks. This is repeated to get a checkerboard pattern. At the bottom is a floor made of ~400 signs placed against each other. From what I can tell it may be caused by the flowing water or the signs. When it crashes it will continue to repeatedly crash for a while before finally going away. If I look down at the ground it seems to help but I haven't really been able to confirm that. It also goes away if I leave the farm area. Nothing shows in the server log other than my character disconnecting so it seems to be client based.
I am getting this all of a sudden as well. One second everything is fine, now I can't walk around the area. It happens to my same account from multiple computers.

No, the best way was how it worked before. Many people have machines already set up that use the position you land after leaving the cart trigger other things. There is no need to change things now.
Now that we have repeatable steps, hopefully someone at Mojang can work on this. My results were the same, lots of checkerboard water = crash. A reduced number of them it doesn't. Not sure if it's the water or the signs holding the streams up.
