[Debian-astro-maintainers] Bug#1010195: astroquery: autopkgtest regression: No module named 'PIL'

[Paul Gevers]

Source: astroquery
Version: 0.4.6+dfsg-1
Severity: serious
User: debian-ci at lists.debian.org
Usertags: regression

Dear maintainer(s),

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

                        pass            fail
astroquery             from testing    0.4.6+dfsg-1
all others             from testing    from testing

I copied some of the output at the bottom of this report. To the 
bystander it looks like a new dependency was missed.

Currently this regression is blocking the migration to testing [1]. Can 
you please investigate the situation and fix it?
