+Subject: [PATCH] a11y: fix race condition on atspi startup on Wayland
+
+This amends db346e711c9af50566c234cfc21199680e6cb499 .
+
+Previously we could race between dbus connecting and our "manual"
+enabled call since we didn't take into account whether dbus is
+connected or not.
+
+This lead to scenarios where opening an application (in particular under
+Wayland) would result in the application not being able to register on
+the a11y bus because registration was attempted too early.
+By simply taking connectedness into account we'll make sure to not
+run registration too early anymore.
+
+Pick-to: 6.5
