Are you sure this isn't a case of Gmail de-duplicating the message in your inbox and actually showing the message in your sent folder (which would have the Bcc fields visible)? Gmail has a habit of doing this sort of thing to save space. Can you try testing this by sending a message with Bcc to two groups, with one of the addresses being a *different* account that you control?
Yes, it is apparently Gmail's doing, although the message where I saw this apparent bug was not in the "sent" folder, it arrived in Gmail's (and thus Thunderbird's) INBOX, which is what threw me. I tried your suggestion, using an email addressed to me that was not the initiating email, and it arrived at that address without the exposed addresses, as it should. It still comes back to the initiating email's inbox with the addresses displayed, but that's ok. My sincere apologies for wasting everyone's time.. Please close this bug as invalid.

Yeah, what happens is that Gmail "receives"* the message in the inbox and sees that it's very similar to the sent message. Then it deletes the inbox message and just makes it show the message from the sent folder. It's really confusing, and one of several reasons I've been looking for an alternative to Gmail. * Mail from a Gmail account to another Gmail account doesn't use SMTP as far as I know. It's just a database transaction.
