+Subject: [PATCH] ibusManager: Don't pass undefined callback to ibus
+
+Since commit 551e8278416, we don't always pass a callback parameter.
+However passing it on as undefined to ibus doesn't work, as gjs doesn't
+accept that as a valid callback value and throw an error. As a result,
+we can end up with no layout selected in the keyboard menu and an "empty"
+indicator. Fix this by explicitly passing null if no callback has been
+provided.
