I found yet another bug in the paypal software. (Information removed to avoid its being made available to Nasty Horrible Dishonest Sellers, as per OP's request)
This is just one of MANY bugs I have found. This one was simple to find.
On a side note, Paypal called to interview me for a position in their QA department yesterday, but it did not go well. If they only knew everything that I know, they'd hire me on the spot but instead they felt I was not qualified, even though I have found more bugs than they have.
I also know how to defeat the fraud detection engine and make a purchase using a TOTALL BOGUS CREDIT CARD and have them mark the transaction "OK to Ship"
I won't disclose how that is accomplished because of the legal implications. I have not defrauded anyone, but have used a separate account on ebay to test this against one of my listings that I was able to successfully purchase and pay for using a fake credit card number.
