Bitcoin address error

[Jeremy West spendbitcoins.com]

I've had a strange occurrence with customers a few times and I'm wondering if it's a known issue.

The situation goes like this: When I paste the bitcoin receiving address into the "Pay to" field on my (official Satoshi) bitcoin client, a different bitcoin address populates the "Label" field. When I click "Send" the address in the "Pay to" field turns red, and no send occurs.

I have then tested sending 0.01 to the address in the "Label" field and found that it was a valid bitcoin address, but I have yet to hear back from any customers whether they have received this test bitcent or not (I have checked blockchain.info and it does appear in the blockchain).

Is this a known issue? What's going on here? Just wondering, as it's quite the mystery to me.

What version?

Have you changed anything since the last time you used the client where it worked successfully?

Is it possible there is a tab or other non-printable character in the clipboard contents?  (e.g., try pasting to notepad or editor and then copying contents back from that paste).

0.5.2

No. And it works successfully now 99.9% of the time. This has happened maybe 3 times over the last few weeks, and I've just got a new address from the customer and sent successfully (so it's not really a problem, just a mystery).

Is it possible there is a tab or other non-printable character in the clipboard contents?  (e.g., try pasting to notepad or editor and then copying contents back from that paste).

Hmmm... I tried this. Nothing showed up in notepad, and the same error occurred when I repasted from notepad.

Here's the latest address it happened with if anyone else wants to donate satoshis to the mystery:
