[Matthias Klose]

Package: src:python-yamlfix
Version: 1.19.1-1
Severity: serious
Tags: sid forky
according to
https://ci.debian.net/packages/p/python-yamlfix/
the autopkg tests fail on several architectures

some of these might be regressions, some not. But please fix that to let 
the tests pass on all release architectures.
