Crashing due to typing on a server

Put the summary of the bug you're having here

What I expected to happen was...:
My goal was to ask the people on this server if they have found any horses in their single player worlds. Just a regular question

What actually happened was...:
I was just on this server, Minecraft Infected, and is started to type and as soon as I clicked enter my game crashed.

Steps to Reproduce:
1. go on s1.mcinfected.net
2. type anything
3. game crashes
I don't know why this happened but I really need it to be fixed because I am an active player on this server.
