[PATCH v2] python: Encode query string as a utf-8 byte array

[Sebastian Spaeth]

If we pass in an unicode instance as query string, we would probably get
weird behavior (and indeed do so, see mail
id:"20110707113700.GA16347 at megatron"). If a unicode instance is passed
in, make sure we encode it properly to an utf-8 encoded byte string.

DOH, I should test my patches for typos before actually sending them off. This one should be fine.
