+ From what I looked in Google, they are all the latest versions.
+I solved the issue uncomenting those lines and adding this:
+
+AutostartCondition=GNOME3 unless-session gnome
+
+in /etc/xdg/autostart/polkit-gnome-authentication-agent-1.desktop, as
+explained here:
+
+http://www.linuxfromscratch.org/blfs/view/svn/gnome/polkit-gnome.html
+
+Is this right for Mageia, or should the tags "GNOME3" and "gnome" changed
+to something else ? Is this worth a bug report ?
+
+TIA
