    Hide the screenshot widget when it cannot be loaded
    
    This is mostly for Ubuntu, where we assume that there exists a screenshot for
    all packages without checking first.
    
    It does make the details page flash after a split second for some applications,
    but this is preferable to a 800x600 empty space.
