This could explain the null > pointer. > that could also be a problem, however GetObject() returning NULL should mean that no object with the reference numbers given to the method was found in the PdfDocument or PdfVecObjects your PdfObject belongs to, so please check if this is the case (no such object exists). Only if it isn't, you could have found a bug in PoDoFo.
