[Python-modules-team] Bug#954812: pythonmagick: autopkgtest regression: cannot import name '_PythonMagick'

[Paul Gevers]

Source: pythonmagick
Version: 0.9.19-6
X-Debbugs-CC: debian-ci at lists.debian.org
Severity: serious
User: debian-ci at lists.debian.org
Usertags: regression

Dear maintainer(s),

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

                       pass            fail
pythonmagick           from testing    0.9.19-6
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.

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

[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
pythonmagick/0.9.19-6. I.e. due to versioned dependencies or
breaks/conflicts.
