If you are viewing the file seite7.pdf, you can see text sections which are preceeded with a bullet. If this file is converted to PDF ( gs -sDEVICE=pdfwrite -o out.pdf -dNOPAUSE -dBATCH seite7.pdf ) , the bullets are shown as black rectangles. The conversion to other formats like TIFFG4 or Postscript works fine!

The 'bullets' are in fact rectangular black images drawn with a soft mask (!) to produce the curves. I see that gs 8.64 does indeed produce (large) solid black rectangles instead of small circular black bullets. Using current code results in correct output for me, it looks like this has been fixed as a result of the extensive work on soft masks.
Unfortunately the soft-mask changes are extensive and generating patches for previous releases of Ghostscript for these changes is not possible. We'll be releasing a new version in August that will incorporate these changes.
