That was what I initially thought.
But the fact remains that it's stumbling on messages, even though I've asked for them not to be backed up.
And, upon some experimentation, I've found that it stumbles on non-attachment messages, as well.
In any case, I'm guessing that you're recommending deleting messages before any backup, because this is a problem with OS 4.5?
