Bug#913847: python-xarray: failing autopkgtests

[Jeremy Bicha]

Source: python-xarray
Version: 0.11.0-1
Severity: important

python-xarray's autopkgtests are failing.

https://ci.debian.net/packages/p/python-xarray/

This is sort of a regression, but for unrelated reasons, the
autopkgtest was failing for the previous version too. Therefore, this
isn't blocking the migration to Testing.

Thanks,
Jeremy Bicha
