The assert triggers because the PDF to be processed contains a /Rotation key which is not equal to 0, 90, 180 or 270.
Basically there are three possibilities: 1) The pdf uses a value not allowed by the pdf specification. 2) The value is close, but not exactly equal to one of the above rotation values 3) The value is not normalized to [0;360) but is e.g. -90. So to fix this I have to know what value the offending PDF uses instead, maybe you can attach the file? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1154318 Title: pdftopdf assert failure: EPSON-Epson-Stylus-SX430: filter/pdftopdf/qpdf_pdftopdf.cc:34: Rotation getRotate(QPDFObjectHandle): Assertion `rot==0.0' failed.
