When pdftocairo ist used with libcairo2-1.15.12-1 -- which (AFAIK) contains the bug I linked above -- to output a pdf file (as pdftopdf 1.21 will do!), it would be no surprise have a corrupt pdf after pdftocairo, which gs then rightly will complain about; esp. the ET -thing is the one things such a buggy libcairo2 will produce.
The only thing form-flattening has to do with it, is that pdftopdf 1.21 would only call pdftocairo when a form is present in the pdf. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1817033 Title: Unable to correctly print PDF file: Error: Ignoring spurious ET operator.
