rpurdie pushed a commit to branch master
in repository bitbake.

    progress: Ensure missing start event is fired
    
    The init function of the parent class fires a progress event for 0
    progress rather than a start event. UI code was assuming that progress
    events should always have a start event first. This change ensures that
    the start event is correctly generated.
    
    This fixes crashes that were seen in knotty in some configurations.
