That would not be my conclusion.  My primary conclusion would be 
user error.

I cannot account for why the stroke on a box would be one color 
while the fill is another.  The only explanation I can give to 
that is that you changed the stroke color, but not the fill.

This is unlikely to be a PostScript error, and neither is it 
likely to be an error in Ghostscript.  Indeed, when I look at the 
SLA file, I see:

The square labelled ``Black CMYK'' is Black fill, Black stroke
The square labelled ``Black RGB'' is Black fill, Black RGB stroke
The square labelled ``Rich Black CMYK'' is Black fill, Rich Black 
(spot) stroke
The square labelled ``Total Black CMYK'' is Black fill, Total 
Black stroke

In addition, Rich Black is identified as registration for some 
reason.  When I turn it off, the stroke appears on all 
separations.

That seems like the opposite behavior of what I would expect.

But unless Scribus uses Ghostscript to output to PS, it's either 
user error or a problem with Scribus.

The registration thing is really throwing me.
