ghostscript-pdf-collection.patch

This patch seems to fix it (found using git bisect).

From upstream revision 10008.

commit 6e93f4ded61a1d21f60dd42273a7de0a908d1076
Author: Alex Cherepanov <alex.cherepanov@artifex.com>
Date:   Wed Aug 19 16:22:08 2009 +0000

    Process embedded files as a portable collection only when /Collection
    attribute is defined in the document root. Bug 690709.
    
    DETAILS:
    Collection atribute is marked in the spec as optional because a PDF file
    need not to be a portable collection but every collection has /Collection
    attribute.
    
    DIFFERENCES:
    None.
