+ * gst/playback/gstplaybin.c: (add_sink), (dummy_blocked_cb),
+ (setup_sinks):
+ Block the subtitle bin output queue before ghosting it and linking,
+ then unblock after. This avoids spurious not-linked errors caused
+ by the queue starting up (because it gets linked when it is ghosted).
+ Fixes: #350299
