> O.K I have tracked it to encrypted pdf.
> If the master password is set , but the pdf document allows various  access options,
it appears the code does not clearly check the options & calls decompression of sections
that are encrypted, hence the error.
> I can be fixed by tightning up on the code checking the "security" flags
