Downstream bug report:
https://bugzilla.redhat.com/show_bug.cgi?id=1752785

This begun to show with glib2-2.60.7-1, glib-networking-2.60.3-1, but also with a Flatpak version (see the duplicate bug of the upstream bug).

As the assertions is hit in a dedicated thread of glib-networking I doubt there's an issue in the application itself. I'd be happy if you can prove otherwise.
