Newly added Google accounts don't work: The specified session has been invalidated for some reason.

This is my GOA/EDS version but it's likely to have been broken by something else I think:

gnome-online-accounts:
  Installed: 3.32.0-1ubuntu1
  Candidate: 3.32.0-1ubuntu1
  Version table:
 *** 3.32.0-1ubuntu1 500
        500 file:/srv/mirrors/ubuntu eoan/main amd64 Packages
        100 /var/lib/dpkg/status

evolution-data-server:
  Installed: 3.32.2-2
  Candidate: 3.32.2-2
  Version table:
 *** 3.32.2-2 500
        500 file:/srv/mirrors/ubuntu eoan/main amd64 Packages
        100 /var/lib/dpkg/status

Existing accounts work fine, but if I add a new account using gnome-control-center or gnome-calendar, then it doesn't work. Calendars don't sync and Evolution can't retrieve mail/contacts, etc. In the journal there is:

Aug 12 12:00:37 raleigh.home.orangesquash.org.uk gnome-calendar[8276]: source_credentials_required_cb: Failed to authenticate '<email address hidden>': Error reading data from TLS socket: The specified session has been invalidated for some reason.

I think that's an error from glib-networking.

I tried on eoan only, so far (a clean system and my real one). As first steps maybe we need to try disco, and maybe also downgrading glib-networking. Or upgrading it: there is a new release waiting to be packaged.
