Bug#963818: numpy breaks python-fabio autopkgtest: fabio.test.codecs.test_brukerimage.TestBrukerLinear fails

Dear maintainer(s),

With a recent upload of numpy the autopkgtest of python-fabio fails in
testing when that autopkgtest is run with the binary packages of numpy
from unstable. It passes when run with only packages from testing. In
tabular form:

                       pass            fail
numpy                  from testing    1:1.19.0-1
python-fabio           from testing    0.10.2+dfsg-1
all others             from testing    from testing

I copied some of the output at the bottom of this report.

Currently this regression is blocking the migration of numpy to testing
[1]. Due to the nature of this issue, I filed this bug report against
both packages. Can you please investigate the situation and reassign the
bug to the right package?
