The definition of GST_MESSAGE_DURATION IS "The duration of a pipeline
changed. The application can get the new duration with a duration
query." There's no guarantee it'll be emitted.
The standard practice for querying duration is to wait for the
pipeline to have prerolled (PAUSED or PLAYING) and then query the
duration.
