Hi Maintainer
Since the upload of python-xarray 2023.08.0-1, the autopkgtests of
sarsen are failing [1]. I've copied what I hope is the relevant part
of the log below.

I think that this is a regression in xarray v2023.08.0.
I have tested sarsen with the latest development version of xarray from
git main, and it works correctly.
Seems like the lasted version in unstable indeed works as it should in
this respect.
