There are two PDF files that needs parsing by thumbpdf:
* the original PDF file to get the MediaBox.
* an internal PDF file with the thumbnail data.
The second case is fixed in version thumbpdf 3.11.
The first case can't (at least, thumbpdf.sty generates a warning),
but this case is less problematic, because thumbpdf uses a default
resolution in case of an unknown MediaBox.
