pyzor problem with fedora25

[Alex]

Hi,

I'm seeing the following warning with fedora25 and
pyzor-1.0.0-9.20160210gitf16e1b6.fc25.noarch with
amavisd-new-2.11.0-4.fc25.noarch.

Jun 27 09:21:40 mail01 amavis[19733]: (19733-10) _WARN: pyzor: check
failed: internal error, python traceback seen in response

Is the pyzor from 2016 the latest version? There seems to be some
changes within the last few months on the github
(https://github.com/SpamExperts/pyzor), but are they significant?

How can I troubleshoot this?

Is amavisd-new-2.11.0 from more than a year ago the latest?
