    giscanner: Fix GtkDocAnnotations implementation
    
    Lesson to be learnt: *NEVER* have a try..except block that catches all
    exceptions and turns them into warnings that are silenced by default.
    
    There was a syntax error in this class implementation that made all
    annotation parsing fail silently.
