           Summary: Error: /rangecheck in --.execform1--
           Product: Ghostscript
           Version: 8.71
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal

I am using a combination of Ghostscript and iText to do some basic PDF
manipulations.

My process is the following:

1. The input PDF (can be any variety of PDF) goes into Ghostscript for
distillation to remove hidden layers and PDF 1.5+ features.  Here's the command
I'm using for this testcase:
gs -dBATCH -dNOPAUSE -sDEVICE=pdfwrite
-sOutputFile='cyan-20-box.ai.distilled.pdf' -c '.setpdfwrite' -f
'cyan-20-box.ai'

2. Import the Ghostscript-distilled PDF with iText and write a new PDF from
that page.  See the included Java code (it's pretty short and nothing special
is being done).

3. Render the iText-generated PDF with Ghostscript.
gs -sDEVICE=nullpage -f cyan-20-box.ai.distilled.pdf.itext.1275078045895.pdf

This works okay most of the time but newer Illustrator PDF-compatible files
with transparency seem to be problematic.  At step 3, Ghostscript fails with
the following error:

I've checked the iText-generated file that goes into Ghostscript with Acrobat
Pro 9.3 Preflight and it validates fine and prints fine so I think this is a
Ghostscript issue.
Ghostscript has no problems rendering the initial Ghostscript-distilled file
(cyan-20-box.ai.distilled.pdf).
