Tried to login from a debian 8 machine to a non wmf wiki with this version of pwb:
```
Pywikibot: [https] wikimedia-pywikibot.git (6f79910, g9698, 2018/06/16, 06:46:05, OUTDATED)
Release version: 3.1.dev0
requests version: 2.11.1
cacerts: /etc/ssl/certs/ca-certificates.crt
certificate test: ok
Python: 2.7.9 (default, Jun 29 2016, 13:08:31)
```
Returns this exception, which I have no clue to do with:
```
