Try this:
SELECT (surname || ', ' || firstname || ' ' || secondname) as fullname,  title_pre, surname, firstname, secondname IS
NULLFROM person;
 

You'll find that when secondname is null, so is fullname. Instead of 
your original query, do (untested):

SELECT (surname || ', ' || firstname || ' ' || COALESCE(secondname, '')) as fullname, title_pre, surname, firstname,
secondnameFROM person;
