Comment 7 for bug 121341

* update-manager, update-notifier and restricted-manager either already run during an upgrade, or they should be started only after the package is configured; apport is started *during* the update. so there is a difference.

* python-support has extensions located at two different locatations, which are both not part of the directory which is found on sys.path; splitting a package in such a way causes differences in the import order. changing the upstream behaviour is no option.
