Fails to parse valid png with 'invalid bit depth 1'

[YenTheFirst]

The attached image appears to be a valid png (browsers and image editors can open it), but PNG.js can't parse it, returning an error 'invalid bit depth 1'

(the image here is a 256x256, all-white image. github gives the url of https://f.cloud.github.com/assets/444387/117015/31671a54-6c17-11e2-902b-a60e71ec1814.png)
