That's all too true. And a good reason not to use too short exposure
times. The more time the shutter stays open, the less is the influence
of uneven shutter movement.
But of course it's a pity that the vignetting correction model can't
cope with this kind of uneven lighting. Should be possible though, much
the same like vignetting correction works, too...
