    objects: Catch OSError inside DirectorySource.get_items()
    
    When we try to load a directory that doesn't exist, we catch the error
    and print it, rather than leaving it to a bigger exception spill
    higher up.
    
    Right now it's the responsibility of the User to configure directories
    correctly.
