Internal Exception: io.netty.handler.timeout.ReadTimeoutException

I will get this error occasionally when trying to join a server: Internal Exception: io.netty.handler.timeout.ReadTimeoutException

EDIT: As seen on this post, it generally happens for people with worse connections, though I never got this error in previous versions.

EDIT: It has apparently been confirmed that even with faster internet speeds, the error still occurs. Also, as pointed out in this post, it happens frequently when trying to connect to your own server too, even when using a port-forwarding program like Hamachi. This error has only been occurring since 13w41a.

EDIT: This bug is still prevalent (and really frustrating), although it does not occur as often. I have gotten this error many times since 1.7.4 release.
