+Subject: [PATCH] gapplication: Initialize backend before withdrawing
+ notifications
+
+Make sure to initialize the notification backend in
+g_application_withdraw_notification() the same way as is done in
+g_application_send_notification().
+
+This makes it possible for an app to withdraw notifications it has sent
+in a previous execution of the application.
