Package: python3-twisted
Version: 17.4.0-2
Severity: serious
Hi,
When using python3-twisted from backports (18.7.0-2~bpo9+1), I get
the following error:
Traceback (most recent call last):

I had python3-attr 16.3.0-1 installed. If I upgrade it to
17.4.0-2~bpo9+1, the problem goes away.
I'm filing this against 17.4.0-2 since I think it applies to all
versions, including the version in testing.
