<exception>.message is no longer a thing in Python3

I've encountered today an error, looking like:

```
'UnlockError' object has no attribute 'messsage'!
```

It look like we still have some small Python2 remains, as
<exception>.message is no longer valid syntax in Python3 (surprised that
the linter didn't catch that).
