Funny idea to call this a bug in Python. What your code is asking for is to
decode the object you pass in using the "latin-1" encoding. Since a list is
not something that is "encoded", let alone in latin-1, you get an error,
and actually a rather clear one.

Note that this is not specific to Python3.3 or even 3.x. It's the same
thing in Py2 when you call the equivalent unicode() function.
