STR: * send a SMS to one contact => the throbber appears, then disappears as soon as the message is sent * click on back arrow * click on the contact again => the throbber is back Sometimes it does not happen if you do this steps fast. To make it appear, I usually wait a few (5 to 10) seconds before clicking on the back arrow. Then it happens all the time, and the SMS that didn't have the throbber have it back as well. This may be related to Bug 822055. I believe we can't ship with this because a user could think the SMS wasn't correctly sent, so I'm nominating this.

David, I'm not sure at all that this is the same bug, because I don't experience the same behaviour as you're describing in Bug 822055. I have no duplicate message. So reopening.

You don't have duplicates all the time, often the first time.
