Whenever I open up the server list, there is always at least one server that has a communication error.
Every time I refresh the server list, the server that previously had the communication error no longer has it and another one does (it appears as if it's random).

I know that this is a bug because this doesn't happen when I'm using 1.5.2.

Step to Reproduce:
1. Launch Minecraft.
2. Open up the multiplayer menu.
3. Notice that at least one server has a communication error.
