  1. check for definedness before calling ->parse

    leejo committed Jul 17, 2014
    on $_[1] in sub scrub, otherwise we get:
    
      Use of uninitialized value in subroutine entry
    
    which isn't helpful and fills up logs. really scrub shouldn't be
    called sans a second argument, but probably a good idea to do the
    right thing here too
