I have pdfshuffler installed from xubuntu depository. When I modified pdf document that I have scanned and try to save it, the following message is displayed - unsupported operand type(s) for +: 'int' and 'IndirectObject' - and the save fails.
I can do the same operation on a pdf file created by libreoffice and the save operation works.
To try and solve this I first uninstalled the xubuntu depository version and did a fresh install from the pdfshuffler-0.6.0.tar.gz downloaded from Sourceforge. Initially I could not execute this programme but after reinstalling the xubuntu version I can run version 0.6.0 (the xubuntu version is given as pdfshuffler 0.5.99~svn75-0ubuntu1).
So this very useful programme is less so because the crop feature is most required for tidying up scanned pdf's.
Is there any way of solving this?
