Updating screen events - LAN moving

This error is similar to MC-31222, however before I even join a server.

Reproduction:
1.Make sure a lan server is running, preferrably by another account and computer.
2.Press the Multiplayer Option
3.Click on the lan server as it appears at the bottom of the list.
4.Hold shift and press the "up" button.
5. (Ocassionally) If this doesn't work try selecting another server or something.
At this stage the launcher should be frozen for a bit and then reopen with crash reporter.

This is as current 1.7.10 and 1.8-pre3.

The second attachment (crash report.txt) is the 1.8 crash.
