Applied to master, thanks. However, could you follow-up with upstream?
They re-opened a MR at
https://gitlab.gnome.org/GNOME/glib/-/merge_requests/3606 but then had
to close it because it broke the build in some situations. If you could
have a look and submit a new iteration of the patch upstream, it'd be
nice.

Thanks!

Thomas
