Narrative:

During approach; when flaps 25 were selected; EICAS 'le slat disagree' and associated caution light came on. Aircraft systems appeared to be otherwise operating normally. Decided not to declare an emergency with ATC due to the distraction this would cause with a very short time left until touchdown. We performed QRH actions and landed without further incident. Left flaps out and notified maintenance. A couple of points I'd like to make: this turned out to be a non-event; in large part because I had a third pilot in the cockpit who pulled out the QRH and read us the procedures while the first officer was flying and I was monitoring/fixing. It doesn't get much safer than that. On a different note; I was surprised to see that the aircraft dispatched on time. It was signed off as no malfunction even though I left the flaps out and the caution light/EICAS message were still present when we left the aircraft. Event though it was apparently a false indication problem; there could be a much more serious outcome if it happens again under less optimum circumstances; such as a short runway. This aircraft has a history of this problem.
