Publishing to WordPress intermittently results in empty posts

Airstory received a support request this week, where the author would publish a document to WordPress and end up with a new, empty post (I've verified that it was indeed a blank post, and not Airstory erroring and showing a blank page).

The user was logged into WordPress (as evidenced by the fact that a post — empty or otherwise — was created. She tried it again the day following my email, and was unable to reproduce the issue (but had experienced it multiple times ahead of contacting support).
