Mojang have release a new minecraft 1.7.8, to fix some crashes that some people had encountered. It’s a update came out a little while ago, and I thought I would share what I found. with an important bugfix to fix some server crashes, and to resolve some skin related issues (including more crashes).
Minecraft 1.7.8 Client and Server Download. This is a relatively small update from 1.7.7.

Please make sure that you are in the correct server mode (online mode/offline mode) when you start the 1.7.8 server for the first time, because profiles are not compatible between these two server modes.
