TypeError: must be str, not bytes

This should be fixed in 2.0.1 (because #90 and #92 were merged).

[isislovecruft]

Okay… this wasn't fixed with the changes from #92; it got more broken for Python3.

@doktorstick Thanks for reporting this issue! I just re-ran your example with Python3.4 after merging the above commit 43164fa into develop and it works just fine now, so it'll be fixed in python-gnupg>=2.0.1.
