Yeah, use my byte warning mode of Python 3.0. Before your time in the
core team I had a long discussion with Guido and a few others. The
conclusion of the discussion was the byte warning mode.
./python --help
-b : issue warnings about str(bytes_instance), str(buffer_instance)
and comparing bytes/buffer with str. (-bb: issue errors)
By the way buffer_instance should be renamed to bytearray.
./python -bb

Type "help", "copyright", "credits" or "license" for more information.

Traceback (most recent call last):

BytesWarning: str() on a bytes instance
[41030 refs]
"Decoding" the "db.DB_VERSION_STRING" byte string would solve the error,
but I rather prefer to know WHY I am having this issue at all. My
Python3.0 "str()" has no any issue with byte values:
It has no issues because Guido wanted str() to successed. Any comparison
or conversion of a byte / bytearray instance with / to str is most
likely a bug or design flaw in the application. The byte warning mode
helps to discover hard to find bugs like "" == b"".
