Adobe Acrobat XI crashes when combining or printing a PDF created by iTextSharp

[doml57970821]

Adobe Acrobat dc, X, and XI all crash when attempting to combine PDFs if one of them was created by iTextSharp. We attempted to print to PDF the iTextSharp document but it crashed again. It also did not work for another user on a different computer. In the end we printed to PDF using the Chrome browser. Print to PDF also worked in Kofax Power PDF. Anyone know a way to get Adobe to work with these so we do not have to print to PDF with yet another software first?

I've attached a screenshot with info about the PDF in question.

You did try with a current version of Acrobat (Acrobat DC)? What is your version number?
