My guess is that you've somehow created the collision shapes as static instead of dynamic. Bullet uses the static classification for objects that never move. If you have two objects that never move, Bullet will assume they never collide.
Although I've done quite a bit of work in the past with Bullet and osgBullet, I would not consider myself a Bullet expert. This is really just a guess. Since the warning comes from Bullet, the Bullet forum might be a better place. osgBullet also has its own discussion group.
