This also happens to me regularly, I've submitted logs to both biteSMS and lock info and I thought that it had gone away after the last updates to both of the betas. It has returned with regular frequency over the past couple days and can be quite annoying. I also keep getting repeat mail notifications and it appears that it's just old emails that I have flagged. I'm sure they're aware of this and are hopefully working on a fix. I guess this is part of the joy of having Beta releases.
