[Python-modules-team] Bug#953232: python-qtconsole: autopkgtest regression: No module named 'IPython.core.inputtransformer2'

[Paul Gevers]

Source: python-qtconsole
Version: 4.6.0-1
X-Debbugs-CC: debian-ci at lists.debian.org
Severity: serious
User: debian-ci at lists.debian.org
Usertags: regression

Dear maintainers,

With a recent upload of python-qtconsole the autopkgtest of
python-qtconsole fails in testing when that autopkgtest is run with the
binary packages of python-qtconsole from unstable. It passes when run
with only packages from testing. In tabular form:
                       pass            fail
python-qtconsole       from testing    4.6.0-1
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?
