Created attachment 7882 [details]
sample file to show the problem

I have an eps file made by my application.
I ran ps2pdf to convert it to a pdf.
When I try to view the pdf with gv, gv gets errors because pdf2dsc fails.
With the attached file, run
bunzip2 < testcon.eps.bz2 > test.eps  
ps2pdf -dEPSCrop test.eps test.pdf
pdf2dsc test.pdf
Error: /rangecheck in --get--
I am using gs9.04 on Linux.

I think that it is due to the numoget call in pdf2dsc.ps when .hasPageLabels is true and it tries to extract a label from PageLabels.

The pdf has
1 0 obj
<</Type /Catalog /Pages 3 0 R
/PageLabels << /Nums  4 0 R >>
/MarkInfo<<
/Marked true
>>
/Metadata 36 0 R
>>
endobj

4 0 obj
[0 
<</P(1)>>]endobj 
36 0 obj
<</Type/Metadata 
/Subtype/XML/Length 1513>>stream

endstream
endobj

The generated pdf views correctly with gs-9.04, evince-2.32.0, xpdf-3.03, and acroread-9.4.2.

The eps crashes old versions of acrobat distiller due to the format of the CreationDate DOCINFO entry.  More recent versions of acrobat distiller process the file but produce a pdf with some text missing at the top.

If I remove the line
[ /Label (1) /PAGELABEL pdfmark
from the eps, then pdf2dsc doesn't get errors on the pdf.

Add missing dereferencing of indirect /Names and /Nums attributes.
