permissions_create_role not working

On my installation of mySQL (5.5.18) the simple sql creating role is not working.

In the code it is:

db_query("INSERT INTO {role} VALUES('', '%s')", $role_name);

However Drupal (actually mySQL) complains about the first argument being ''. I would change it to:

db_query("INSERT INTO {role}(name) VALUES('%s')", $role_name);

which seems more "standard" and corrects the error.
