I tried upgrading a GNOME virtual machine from an outdated version of
trixie to current trixie, and that did not reproduce this problem.
The only packages that were held back by `apt upgrade` were unrelated to
gobject-introspection (related to the Boost version transition).

According to a reply sent privately, the answer is that it was synaptic
and not apt that removed (proposed to remove?) these packages.

Please could you answer this? It will help to figure out why this
happened. Please reply to the bug address rather than to me personally,
so that other team members are able to help you.

It would also be helpful to see the output of:

    apt --dry-run dist-upgrade

which will help us to see why apt is now holding back these packages.

Thanks,
