    # Only load YAML serializations that are present, not empty strings

    # This should normally receive a Schedule object.
    # In some unknown circumstance that I can't reproduce, it would save an
    # already-dumped serialized YAML Schedule string into a YAML string
    # wrapper, effectively double-bagging the YAML. I only assume it receives a
    # String when loading a bad YAML value from the database, which then
    # propagates and re-re-serializes itself into YAML on every save.
