I type something in chat and send it by hitting enter and I crash immediately.

Minecraft crashes after I send a chat message using enter to send it.

What I expected to happen was...:
Sending a message by hitting enter and just having it send like normal.

What actually happened was...:
I hit enter to send the message and minecraft crashed.

Steps to Reproduce:
1. Hit "t" to open the chat window.
2. Type any message.
3. Press enter to send it.
