This patch fixes yet another instance of bad PDF data, specifically a case where the `BBox` array contains indirect objects (i.e. `Ref`s). Fixes the missing image in http://www.int.washington.edu/talks/WorkShops/int_08_37W/People/Franz_M/Franz.pdf#page=24. *Note:* There are missing images on a number of the pages in that file.
