Looks like you have an invalid PDF file. You also have an ancient version of Ghostscript, 9.09 is 5 years old and I'd start by trying the current version instead.

I'd also try just opening the PDF file with Ghostscript to see whether that works, if it doesn't then I'd need to have the original PDF file to say why.

One thing that is relevant, though you may not be able to change it, is; Don't use -dUseCIEColor.
