Losing connection to server when a Minecart Command Block is placed on a powered Activator Rail

Losing connection to server when a Minecart Command Block is placed on a powered Activator Rail.

What I expected to happen was...:
That the players would not lose connection to the server

What actually happened was...:
As soon as the Minecart Command Block was on the powered Activator Rail everyone loses connection to the server. (If a local server the host does not loose connection).

Steps to Reproduce:
1. Run Minecraft as a server
2. Have multiple people on server
3. Place Minecart Detector Rail on Activator Rail
4. Power Activator Rail
(Note: Steps 3 and 4 are interchangeable)
5. Client Crashes

Error: Internal exception: Java.io.IOException: received string length longer than maximum allowed (88>64)

Confirmed for me. I'm surprised it isn't more well-known. Maybe most people aren't getting this? But then what are we doing differently? I'm just using command minecarts normally, just about 2000 blocks from spawn, and I have to remove them in MCedit to get the server working again.

Happening for me too. Exactly the same error too. Doesn't happen in single player though.

I guess it is because of the packets being send from the server to the clients. As the maximum string length for cmdblocks has been increased, they probably forgot to adjust the packets to be able to accept the bigger data.

Confirmed

Remains an issue in 13w41a (and b)

Here's the log file

Any news on if it is a confirmed bug? Or how I can fix this as I am still having this problem

Please force a crash by pressing F3 + C for 10 seconds while in-game and attach the crash report ([minecraft|http://hopper.minecraft.net/help/finding-minecraft-data-folder]/crash-reports/crash-<DATE>-client.txt) here.

How do I do this as I can not enter the game? The game kicks me straight away and displays the message.

Either you manage to delete the minecart with MCEdit or you have to recreate the world with the same seed...
