I would look through you modifications and see if any UPDATE the post table. Or, if any change the input field for the post message. Look at the page source of the edit page. Can you identify easily which posts that you would edit would suddenly turn blank? Is it only from using the Quick Edit or only from using Advanced Edit? Do you have a test site where this is also happening? I think you need to do some testing to figure out exactly when this is occuring. My guess is a modification is screwing up the page source for the form and thus the message text is not getting passed correctly when the update of the post table occurs.
