Game crashes upon entering fullscreen

[darealGameknight14]

Bug Description

Minecraft crashes upon launch. Further investigation upon deleting options.txt reveals it crashes upon entering fullscreen.

Did this behavior use to work in the previous version?

Unknown, it was working fine in the version I was playing on until this afternoon, when it suddenly stopped.

Steps to Reproduce (for bugs)

1. Launch the game
2. If the game is not already in fullscreen, do so from the ingame options or press F11.
3. Game crashes.

This looks like more like a key binding issue; if you bind certain keys such as extra mouse buttons or keys that don't appear on a standard English keyboard then the game will crash on load due to a bug in this version of Minecraft and the game engine it depends on. Can you confirm if this could be the case here?
