I believe that this is a bug in the PostScript renderer used by 
Mathematica because this problem does not appear when the drawing is 
exported as EPS.

When making figures like this you may find it helpful to preview them 
directly in an external application, like GSview, e.g. on Windows use 
something like

gsTempFile = ToFileName[$TemporaryPrefix, "mma_ghost.eps"]

(* no spaces in the path! *)
gsview = "C:\\Progra~1\\Ghostgum\\gsview\\gsview32.exe"

gsDisplay[gr_] :=
	(Display[gsTempFile, gr, "EPS"];
	 Run["start", gsview, "-e", gsTempFile];

$DisplayFunction = gsDisplay

and in GSview, set Options -> EPS clip.

I use this because in the front end the fonts do not appear correctly 
(wrong size).
