Submission + - Short proof of the four color theorem?

easyEmu writes: Today a mathematics paper http://arxiv.org/math.GM/0702261 claiming to be a short theoretic proof of the four color theorem appeared on the arxiv. Such papers appear on the arxiv about once every three months by non-mathematicians who are quacks. According to other papers under this latest author's name, Yanyou Qiao has collaborated with other mathematicians, one of whom I know is very respected in his field of research. Could this be the long awaited arrival of a simple proof, in this case eight pages, of the famous four color theorem, or simply another attempt with a fatal flaw?

My idea of roughing it turning the air conditioner too low.
