This appears to be related to NEI. Last night I had it open in Extended Creative Mode, with items from the XyCraft mod selected. I deleted the string "@mod.XyCraft" from the search window and now I get a crash when ever I open any GUI.

I have tried doing a force update and this does not resolve the issue. I have also tried restoring an earlier backup of the same world that is crashing, and that did the same thing. Only the world in which I changed NEI to Extended Creative Mode is crashing; I can open any GUI in any other world without a crash.
I have about 3 months worth of progress in this world, including getting a Gravity Suit. I would really like to be able to resolve this rather than having to start over.
