    tracker-extract: Do not pass lesser errors as processing errors
    
    The errors sent back to the decorator are meant to be sort of critical/
    disrupting, things that fall upon the normal mode of operation that
    tracker-extract should be prepared for (eg. files we don't have
    extractors for) shouldn't be issued as criticals.
