(Basically agreeing with Darin) The empty string is what I was thinking
would be appropriate for this case. The file/blob spec,
http://www.w3.org/TR/FileAPI/, already allows for an empty string if the
mime type cannot be determined:
User agents SHOULD return the MIME type of the file, if it is known. If
implementations cannot determine the media type of the file, they MUST
return empty string.
