Instructs GStreamer to stop emitting the "sync-message" signal for this bus. See Bus.enableSyncMessageEmission for more information.

In the event that multiple pieces of code have called Bus.enableSyncMessageEmission, the sync-message emissions will only be stopped after all calls to Bus.enableSyncMessageEmission were "cancelled" by calling this function. In this way the semantics are exactly the same as gst_object_ref() that which calls enable should also call disable.

MT safe.
