Hi Leon,
I dont think this is the problem. Vignetting is caused by a light droppoff towards the edge of the image from the focussed light cone. Your images have vignetting but your flats dont seem to remove them or to remove the dust bunnies. As Fred pointed out your flats are too bright and wont help to remove dust bunnies and vignetting.
I might be wrong but if you had light leakage from the back of the camera then you would expect it to be across the whole image and not look like vignetting.
I would try and take some more flats and keep on going until when you look at them you can see the dust bunnies clearly and a well defined light dropoff towards the edges. Then apply these flats and see if they solve the problem.
