1978 is not the publish date of the thesis. The examples (Firefox, JDK 5, OpenSSL 0.9.7) should give away that it's newer, and also the most recent citation is from 2006. I'm not sure why the title page has a 1978 as I can't read Dutch. Google Translate indicates it might be a date of birth of the author, but that's a weird thing for the title page.
