I've posted this question elsewhere (going to close it now) and I fixed it by selecting "Rebuild" from the Mailbox menu. It took a while to complete (see the floating activity window), but once that was done, Archiving worked.
Oddly it worked for me on some messages but not others, and there was no pattern to which worked (from, to, subject, etc.)
Try this and let's see if it works for you too.

Yes this is with Google Apps. I have had to do it twice now, but it works. I rebuild, wait, quit, restart, and it works.
It is a bug, but for now I can work around it. When it works, it works really well.
You really MUST have deleted the account from Mail.app and recreated it, otherwise it does not work.
