I'd say it might be a bad ground if the warning went off just as you were doing something like stepping on the brake. If you've got a bad ground, the brake-lamp current might backtrack into the taillamp circuit and confuse the Adaptive Lamp Monitor that controls your warning system.
Otherwise you might just have a flaky bulb that'* on its way out. I would just wait until it fails permanently...
