Do you have any texture packs installed? If so, what are they and can you provide me with links please?

It's my own texture pack, I upload the version I had played around with and edited a little bit just now for this issue. Here's the link: http://www.planetminecraft.com/texture_pack/nautilus-texture-pack-v12/

The new texture loading system is still very early in its development. The problem here is that the texture packs you are using have invalid files in them (.rtf and a .txt with other data than texture pack data in them). If anything, we should add some checks and better feedback as to why a texture pack is causing a problem or not loading.

It will crash less violently and with more info in future, but you cannot have txt files with invalid data right now.
