[Debian-astro-maintainers] Bug#918625: astropy-healpix: autopkgtest deprecation warning due to new version of python-numpy

Source: astropy-healpix
Version: 0.4-1
User: debian-ci at lists.debian.org
Usertags: needs-update
Control: affects -1 src:python-numpy

Dear maintainers,

With a recent upload of python-numpy the autopkgtest of astropy-healpix
fails in testing when that autopkgtest is run with the binary packages
of python-numpy from unstable. It passes when run with only packages
from testing. In tabular form:
                       pass            fail
python-numpy           from testing    1:1.16.0~rc2-1
astropy-healpix        from testing    0.4-1
versioned deps [0]     from testing    from unstable
all others             from testing    from testing

I copied some of the output at the bottom of this report. Your
autopkgtest fails on a Deprecation Warning. If possible, please fix your
autopkgtest to not do that at all, but at least fix this issue.

Currently this regression is contributing to the delay of the migration
of python-numpy to testing [1]. Of course, python-numpy shouldn't just
break your autopkgtest (or even worse, your package), but it seems to me
that the change in python-numpy was intended and your package needs to
update to the new situation. If needed, please change the bug's severity.

I am going have this regression ignored for the python-numpy migration.

[0] You can see what packages were added from the second line of the log
file quoted below. The migration software adds source package from
unstable to the list if they are needed to install packages from
python-numpy/1:1.16.0~rc2-1. I.e. due to versioned dependencies or
breaks/conflicts.
