pdftk uses the itext library and a mail on its mailing list gave me the right hint: http://thread.gmane.org/gmane.comp.java.lib.itext.general/46855/focus=46859
The printed pdf file is not standard conform [1]. The information dictionary of the document is a direct object, not an indirect reference as in the pdf that works. So this is mainly a bug in the used pdf generator, not in pdftk. However, pdftk should produce a more user-friendly error message. Can you provide the version of the cups / cups-pdf package which you have installed, please?
