Comment 8 for bug 134000

Please correct me if I am wrong, but bug #146943 seems to
suggests that these fixes are not enough.

Over there, fx5 did the following analysis:

python-apt is packaged with python-central.
python-central use dpkg-query to read the package-fields (like Python-Version).
dpkg-query seems to fail, because it is the old (feisty-) version that does know about triggers.
There is a trigger-status for libc6.
