Description of problem: I have a pdf file which I tried to print to pdf with xpdf. The file (print.pdf  -- the default name xpdf gave) is not pdf, it is a postscript file. Furthermore if I look at the file it is a postscript, not a pdf, file. 

If I move the file to print.ps, and run gv print.ps, then gv throws an error

Version-Release number of selected component (if applicable):
xpdf-4.02-1.2.mga7

How reproducible: Always on that particular pdf file
Here is the definition in the ps file created by xpdf:

1 array dup /ImData_44_0 exch def
dup 0 <~LkpkCz+sJ3TzLkpkCz+sJ3TzLkpkCz+sJ3TzLkpkCz+sJ3TzLkpkCz+sJ3TzLkpkCz+sJ3TzLkpkCz+sJ3TzLkpkCz+sJ3Tz~> put
pop
false pdfSetup
595 842 pdfSetupPaper
end

And here is the first instance which I think is the one that throws thatfirst error.
....

xpdf print to PDF should produce a pdf file, not a postscript file. 
xpdf should NOT produce an invalid postscript file. 
(Unfortunately that file is a file with personal and sensitive data in it, so 
I cannot include it here.)
