+Subject: [PATCH] application: Drop support for non-unique mode in headless
+ instance
+
+gnome-shell started allowing only applications that own certain names
+on the session bus to interact with the screenshot interface. While the
+name used by gnome-screenshot is on the allowed list, non-unique
+instances that are used for the headless mode do not own that name. Fix
+this by also making the headless instance unique so it will own the
+name. This however also means that there can only ever be a single
+instance of gnome-screenshot, regardless of headless or interactive.
