[Python-modules-team] Bug#958554: beautifulsoup4: autopkgtest failure.

[peter green]

Source: beautifulsoup4
Version: 4.9.0-1
Severity: serious

The autopkgtest for beautifulsoup4 is failing in both plain unstable tests and testing migration tests, but not in plain testing tests.

 From diffing test logs I belive this was most-likely caused by the update to python-soupsieve
