That's rather due to rounding and not a bug. Lab and 8-bit don't play 
well together. But the Decompose plug-in has no other choice than to 
squeeze the result into 8-bit. (It *might* be augmented by the unusual 
assumption of PAL/SECAM input, but that'd be more of a coincidence.)

Other than that, decompose and recompose are consistent.
