Potential Parsing Error for some PDFs about pdfrw HOT 2 CLOSED

I also wanted to note that I tried the code suggestions that I saw in Issue 8.  
Adding the checks to determine if page.Contents was already a PdfArray seems to 
prevent the error message, but converting this PDF to a Stream and using it as 
an Overlay does not produce the expected results - the output document does not 
contain the watermark.

This is actually two issues. The first has been fixed by code on the master branch. The second is that the watermark file contains compression that is currently unsupported by pdfrw. (This is part of issue #5 )

You can use pdftk to uncompress the file:

pdftk sourcefile.pdf output destfile.pdf uncompress

and then the uncompressed watermark file will work.
