special PDFs which do not get through dispatching
Some PDF files aren't uploaded at all, for instance images attached to outlook emails (by printing them directly from outlook webmail). Tested with fakeprinter on Linux and Win7, both leading to the same result.
Solution was to convert these images to PDF or to print them directly from Firefox/Chrome (file:// URI).
Affected customers didn't want to give me their files to test, so we'd have to test that ourselves.
