FWIW, this bug was stopping the webbrowser from being able to export a PDF to the printing 'app'.
This was due to content-hub using libapparmor to check if the app was able to read the path, and the webbrowser-app using an apparmor manifest which generated a rule with owner in it.
It would be good to get this fixed to prevent other apps using content-hub failing to import/export.
