I'm not too worried about it though given that it only happens for me when the engine is stone cold and at very low speeds.
Not quite sure what you're talking about. The bucking on my MT is only at very low speeds and can be eliminated by pushing in the clutch pedal and than engaging again. This has happened to every MT car I'll ever owned and is due to normal drivetrain loseness.
