Without knowing the details of your tables, it looks fine to me. I suspect there is some reason why your code can't see that record. Maybe it hasn't been committed, or you are running with an unusual isolation level?

UPDATE: Actually, that looks wrong. It should be generating an "IS NULL" there. Do you have the latest Class::DBI?
