+Subject: [PATCH] [applets/devicenotifier] Don't open popup for
+ already-connected devices
+
+The old applet only opened the popup when a new device was attached
+after the applet was loaded, not if there was already a device attached
+when the applet was loaded. This commit brings back the old behavior by
+re-using the approach taken in the old applet.
