In version 0.3.1 and prior, bytestrings can have dirty bytes in them, resulting in the word-for-word comparisons giving incorrect results. Even without dirty nonzero bytes, two bytestrings can compare to equal if one ends with `\"\\x00\"` because there is no comparison of the length. A patch is available and expected to be part of the 0.3.2 release.
