xdg-desktop-portal spams "access denied" messages in systemd journal

[David Osolkowski]

Ubuntu release: 19.10 eoan
xdg-desktop-portal:
  Installed: 1.4.2-2
  Candidate: 1.4.2-2
  Version table:
 *** 1.4.2-2 500
        500 http://us.archive.ubuntu.com/ubuntu eoan/main amd64 Packages
        100 /var/lib/dpkg/status

Expected: Background software and services in the default configuration do not keep periodically failing.

Actual: Messages of the following format appear in the systemd journal once every minute:

Dec 01 15:34:21 hostname xdg-desktop-por[2240]: Failed to get application states: GDBus.Error:org.freedesktop.portal.Error.Failed: Could not get window list: GDBus.Error:org.freedesktop.DBus.Error.AccessDenied: App introspection not allowed

This may be related to GitHub issue 215 in the xdg-desktop-portal project: https://github.com/flatpak/xdg-desktop-portal-gtk/issues/215 They made a change in a newer version that should prevent this message from being recorded more than once, but if there's a root cause that can be addressed that would be helpful.

I believe that this is a bug in xdg-desktop-portal-gtk not xdg-desktop-portal, and already has a bug tracking this issue.
