Cannot run python3 scripts any more

[Tony Arnold]

I've now re-installed my system, but apt is still suggesting to
autoremove the package 'python3-dbus.mainloop.qt'.

Does anyone know, or can tell me how to find out, if this package is
needed in Artful, or is this a dependency bug?

Regards,
Tony.
