Description

I am seeing an issue where multiple trailers exist for a PDF, but the trailer that is being found does not contain a Pages object in the Root.

The PDF does have a trailer that can be read with Pages in the root but the brute force approach needs to be taken when parsing is lenient.

This issue can be seen as being resolved in pdf.js here
