Well a happy if not completely satisfying ending. So alternative readers worked ok, but IT was ok with turning off protective mode and also disabling javascript in adobe reader, considering the relative benign provenance of the pdf's coming into the system (though I am curious whether or not disabling java script is actually *more* secure than a sandbox, i.e. can a system be harmed by rendering a pdf with no java script? -- https://mail.python.org/mailman/listinfo/python-list
