Not really. It is all explained quite clearly in my OP. The only thing I guess I didn't make quite clear was the fact that it was a cancelled transaction and the buyer's payment was refunded and no item was sent. It was an unwelcome purchase with the specific intent of leaving negative feedback, which is indeed what happened, but because of the circumstances, was removed by eBay on appeal.

This is the reason the buyer wants my personal details. She was pretty annoyed that the neg was removed and obviously bears a grudge. I have already been told by eBay that if she sends me harassing emails or attempts any other form of retaliation, to report her to them and they will take further action.

Refer to Clarry's post above yours which refers to the very same buyer. She has already sent him harassing emails even though he never accused her of any wrongdoing by name. Now this person has not only my email address, but my home address and phone number, as well as google images of my home, so perhaps that will help you to understand why I'm so bloody annoyed with eBay right now.
