I have noticed what I think is a symtom when shooting metered manual, with the occasisonal exposure reading that just doesn't make any sense.
I have noticed this on my LX, but in my case the problem is quite mild. It only happens occasionally, and I can "fix" it by just wiggling the ISO dial a little.
It is pretty obvious when it occurs: the meter indicates 1/2000 when I know intuitively that it should be something more like 1/125 or 1/250.
Cheers,
