Dust and debris have caused problems with more than a few cameras. On the Sony P-200 it contaminated the CCD, on the Canon G-7 and G-9 it contaminates the lens. And yes, it is due to the bellows effect created when the lens extends and contracts. That is why I would be very careful indeed, when looking at a G-7 or G-9 on e-bay.
