I have tweaked the process a little to get a better result in Inkscape. 
Rob, at the Inkscape forum offered some help:

He, thinks that the 'Stroke to Path' problem looks like a mathematical 
rounding error. That makes sense to me.

So now, the first thing I do, after loading the .ps file into Inkscape, 
is to scale it x10. I do all of the 'ungroup', 'path to stroke', and 
'union' operations on it and then scale it back to normal size. At 10x 
the size, the 'Path to Stroke' does better at converting the end caps on 
the lines; and, after the 'Union' operation, the 45 deg. and 90 deg. 
corners are smoother on the traces.

You might think scaling 100x would be even better. However, by scaling 
x100 in Inkscape and then doing 'Path to Stroke' and 'Union', a new set 
of problems arise.

gEDA/pcb creates the solid ground plane out of multiple polygons that 
are butted up against each other, and meant to be treated as one solid 
object. At x100 scale, tiny slivers of white background show between 
some of them. They are 'boolean union'-ing into a single object, but 
with long, thin slivers taken out of the solid ground plane. The scaling 
seems to be slightly offsetting the nodes - looks like another rounding 
error to me.

So, x10 gets good results. I am very happy with it.
