Comment 1 for bug 672137

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,
