This is due to the pyPdf toolkit being updated. calibre/ebooks/pdf/writer.py calls PdfFileWriter with a title and author, but that is not an attribute the PdfFileWriter function takes.
Just comment out that line, and make it: outPDF = PdfFileWriter() Don't forget to keep the same indentation, as python will not forgive. Nuisance yes, but easy fix :) Hope that helps, Tom Golubev -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/672137 Title: calibre PDF conversion helper program crashes, leaving output file empty -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
