Creating SimplePDFViewer fails

[dwadler]

I'm getting the following error when trying to process a 2.6MB PDF document of tax assessment data. There were similar but different errors when using PDFDocument, page_one = next(doc.pages())

@dwadler Confirmed. It fails to parse object streams in the file. Not sure what the issue is. Will keep you updated.

@dwadler The document is encrypted.

Encryption is currently not supported by pdfreader.
