Wrong quotes, but I see that is due to using ``'`` in the message, but wrapping is a bit off:

```
logger.debug(
    "Triggering event: playback_error(error='%s', debug='%s')", str(error).decode('utf-8'), debug.decode('utf-8') or 'None'))
```

just with 80 wrapping is more what we want, I would also just consider doing the encoding just once.

Also, you might be able to just drop the debug logging here given that we added https://github.com/mopidy/mopidy/blob/develop/mopidy/listener.py#L17
