      [FIXES]
      - Test for undef streams instead of truth, to allow streams like '' or '0'
        Thanks to Thorsten Schwander for the patch
      - Failed to parse PDF 1.5 cross reference streams where a
        1024-byte boundary happened to fall between "endstream" and
        "endobj" do to a logic error.
        Thanks to Thorsten Schwander for the report and fix suggestion

      [FIXES]
      - Workaround for corrupt PDFs that have 'n' records in their index that \ 
point to byte zero
        of the file. Silently treat those as 'f' records. Yet another case of \ 
Acrobat supporting
        broken PDFs, so the rest of us have to support them too...
        Thanks to Mark Hunnibell for a sample PDF that demonstrated the problem
