No, Acrobat seems to be failure tolerant in that it can analyze the PDFs
structure without consulting the xref table. The xref table is only used
for speeding up analysis of a PDF. It's not really necessary.
Acrobat repairs ('file is being repaired' dialog box) the xref table in
that it calculates the correct indexes. When you save the PDF in Acrobat
after that your PDF will be correct again and should also open in
GhostView.
You've got to fix your indexes in the xref table, I think.
