I think it is correct.
Python doesn't assert that PyErr_Occured is called, it asserts that the error
is cleared before you call back in to another thing that can cause an error.
PythonException will clear the error if there is one, or say "unknown error" if
there isn't one (which should never happen if utf8==NULL, but i'm checking out
of abundance of caution)
