Import pdf creates ASCII garble

I just downloaded the latest LibreOfficePortable (version 3.4.3). When I attempt to open a pdf image, for example in Draw, it's converted into ASCII garble and opened in Write. Does anyone else have this issue?

Note: There is nothing wrong with the pdf. It's an old pdf image I've used in documents before, and it opens just fine in all pdf viewers. It has pdf version 1.4. Unfortunately there's no option to attach files here, but take my word for it.
