I saw the same error. In my case, the solution was to open the Address Book, select "Tools Options...", and then to remove the Global Address List from the listbox with the description:

"When sending mail, check names using these address lists in the following order:"

I think copy operation was failing because the Address Book was attempting to copy the contact from Global Address List back into Global Address List. But removing the Global Address List from the listbox seems to avoid this conflict.

Good luck!
