-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.
