Steps to reproduce the bug

1. Select a photo to send.
2. Compose a message but don't send it.
3. Change screen orientation.

Expected behavior

Draft message should be preserved, and appear in the new orientation.

Actual behavior

Entire draft message will disappear. This happened to me twice in a row this morning. The first time, I stopped composing to pet the cat, then looked back, and my message in progress was mysteriously gone. I started again, moved such that the screen orientation changed, and again, my work disappeared. This time I saw it happen. I tested the steps above to confirm the behavior, and it's consistent.

Weird, an orientation change just now with an empty message box retrieved an MMS draft from an hour ago, which had already been sent.

I've found MMS drafts accidentally by using the back button to navigate backward through the activity stack, something I rarely do, but did once absentmindedly and found very revealing. I wonder if it's a stack navigation mistake.
