625534d7b1417da926f1ced600855ea818d6e01e Give more errors for specific failure conditions (Andrew Chow)
c325f619dd071b5489989f645e42cace8eb23fb4 Return an error from descriptor Parse that gives more information about what failed (Andrew Chow)

Pull request description:

  Because it's nigh impossible to figure out what is wrong with a descriptor otherwise.
