IRC to the rescue! Freenode's #dns and user hawk to be specific.


Turns out, in DNS, an ASCII character-string that's preceded by a 2 byte 
length field *also* includes a 1-byte length field, similar to "Standard 
DNS name notation, but without a trailing NULL byte.

And the 2 byte preceding length field must measure the internal length byte.


I must say, I'm rather unimpressed with all the documentation I've found 
on the issue.
