I have just imported print/pdfarranger, a maintained fork of print/pdfshuffler. If you often have to modify pdf files, please give pdfarranger a try so that we can shake out problems.
py-poppler and pdfshuffler are unmaintained and use py-gtk2, also unmaintained. ok to remove them, say, in one week if no one speaks up? -- jca | PGP : 0x1524E7EE / 5135 92C1 AD36 5293 2BDF DDCC 0DFA 74AE 1524 E7EE
