Crash when using any GUI in game

When I try to use any GUI at all, including vanilla, minecraft crashes. Here's the log:

Appreciate any help, thanks in advance.

This is a known error with XyCraft and NEI. It has been fixed in the 1.5.x version of XyCraft if and when it gets released.

To fix it you need to backup your saves and delete this file.
...\modpackname\minecraft\saves\NEI\local\New World\NEI.dat
