Apparently in Python 3 the line in line.startswith('X-') can be a byte type, which requires different parameters. The article that caused it contains no metadata , only what seems like base64 encoded content. The header or subject has no encoding info.

During handling of the above exception, another exception occurred:

TypeError: startswith first arg must be bytes or a tuple of bytes, not str

I don't understand the first errror. Oh, wait, is it in sabyenc? That would be bad.

the startswith() seems the same as here: https://stackoverflow.com/a/19827633

I assume that sabyenc doesn't do base64 and doesn't find the filename. The exception is from the decoder: https://github.com/sabnzbd/sabyenc/blob ... nc3.c#L614

Then there is a new exception in the ValueError exception handling because of the byte problem.

I'm just downloading all the content in random groups for testing and so far I've had 5 files which have failed for this. It has never happened when I have downloaded specific things.

The sabyenc error is correct, it's just a malformed article or one that we don't support. But then it shouldn't fail later on so we need to do some tricks there. I thought I had wrapped that, but seems we need a ubtou call on it.
