Strange Issue Duplicated DB Queries

[eluser]ludo31[/eluser]
I have also the same problem

Code:

$this->db->select('id');
            $this->db->from('chaussure');
           $this->db->order_by("id", "desc");
            $this->db->limit(1);
            $query = $this->db->get("chaussure");

and I change $query = $this->db->get("chaussure"); by $query = $this->db->get();

and it works
