Working.pdf - newly created blank page with acrobat

Error.pdf - downloaded, I cannot change the process of its creation. I deleted all visible text on the page which did not appear to affect the behaviour of the error

We hit the same issue with next(high_level.extract_pages(pdf_page_path)) calls.

Probably need to call resolve1 on self.attrs["MediaBox"] as well... it's indirect objects all the way down...
