possibly not overly helpful, but I what to add that libspectre is just a thin and sometimes fragile wrapper around Ghostscript. So even if libspectre did not change, maybe Ghostscript did and libspectre did not adjust accordingly? Also libspectre does tend to print some sometimes useful error codes/messages to standard error, so maybe running Evince or qpdfview from a Terminal might help?
Hello,
possibly not overly helpful, but I what to add that libspectre is just a thin and sometimes fragile wrapper around Ghostscript. So even if libspectre did not change, maybe Ghostscript did and libspectre did not adjust accordingly? Also libspectre does tend to print some sometimes useful error codes/messages to standard error, so maybe running Evince or qpdfview from a Terminal might help?
