[Debian-astro-maintainers] Bug#1007827: asdf-astropy breaks gwcs autopkgtest: cannot import name 'assert_models_equal' from 'asdf_astropy.converters.transform.tests.test_transform'

Dear maintainer(s),

With a recent upload of asdf-astropy the autopkgtest of gwcs 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
gwcs                   from testing    0.18.0-2
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 asdf-astropy 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?
