[Debian-astro-maintainers] Bug#1007826: asdf-astropy: autopkgtest regression: 'cannot represent an object', <Cosine1D(amplitude=10., frequency=0.5, phase=1.)

Source: asdf-astropy
Version: 0.2.0-1
Severity: serious
User: debian-ci at lists.debian.org
Usertags: regression

Dear maintainer(s),

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

                        pass            fail
asdf-astropy           from testing    0.2.0-1
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 to testing [1]. Can 
you please investigate the situation and fix it?
