We were able to copy your file to a memory card, and perform an Ingest on that card while applying metadata without encountering an error. I might recommend zipping the file first and then uploading as an attachment to make sure that the file is not somehow being modified when uploaded to our forum.
That said, since the error seems to be conditional on whether or not you are applying a Metadata Template, have you tried applying the template before the Ingest? Have you tried Ingesting and then applying the template? Do either of those thing work or give you an error message?
