There was a problem hiding this comment.
In Python 2 str is the byte array type, so str(json_data) is a noop (the bogus UTF-8 will enter the logging stream). I didn't realize str(b'...') was the same as repr(b'...') in Python 3 until I just tried it, is that what you were intending? What about just ('Logging raw invalid UTF-8 response:\n%r', json_data)?

As pointed out in #1072, malicious clients can send arbitrary
callback_datain callback queries, even bytes that can't be decoded using the utf-8 codec. This would bring the whole bot to a halt.
