What is wrong with this Wikipaedia article about Dirac's monopole?

Question

The article can be found here:

http://en.wikipedia.org/wiki/Magnetic_monopole

The startling error in elementary (undergrad) physics is in the explanation of how Dirac derived his quantization condition for the product of charge and magnetic pole strength. What is it, and how do you correct it? Note that the mistake is that of the author of the article, definitely not Dirac's! This is a worthwhile exercise.

Well, you have to keep in mind that wikipedia is not the be-all end-all site.  Some people who add articles to that site might not necessarily be qualified.  Some of those people are just everyday people who feel like adding an article.
