There is an unhandled error if I try to display page 24 of this PDF:

It's conceivable this may be due to an inconsistency within the PDF, but other viewers seem to handle it correctly.

Your standard fully-functional test viewer.html doesn't display the error in the console, but it does just hang indefinitely until I to move on to another page.

The same error happens in all browsers I've tried (Chrome, FF, Safari in Mac).

pdf.js - using git commit 553928c

Thank you for your help - I hope this is useful.
