Today I tried to join a server. It went to this bluish-grayish screen and then I crashed. I'm pretty sure it was a pluggin server.

What I expected to happen was:
I would join the server and play.

What actually happened was:
The screen went gray for 2-3 seconds and then my Minecraft crashed.

How to reproduce:
1. Click multiplayer on the title screen.
2. Join a server (My server was pluggin, but It might happen with vanilla servers too.) .
3. Crash.
