The PDF preview can't render certain PDFs and will display only blank, white pages.
The problem occurred with scanned documents which where saved with JBIG2 image compression (the default for Acrobat 5.0 and newer).
This is the resulting stack trace:

Saving the file with CCITT Group 4 compression (see screenshot) will serve as workaround, i.e. the preview will be able to render the image, but the parser still outputs an (different) error:
