Replacing error with warn at obj.js#L894 lets the file render, but I'm not sure if that really is a desirable "solution", since it basically moves a potential error to another part of the code-base.

Adobe Acrobat is able to render this PDF file without a prompt upon closure, so I'm not sure if the PDF is in fact corrupt or if we just fail to parse it properly.
