Why don't photons that bend with gravity violate conservation of momentum?

Photons have momentum, gravitational bodies can bend light, thus their momentum changes. Doesn't this violate conservation of momentum?

It's not violated because the bodies that bend the light experience a change in momentum equal in magnitude and opposite to the change experienced by the light. 

Remember that light bends spacetime too.
