773362 - Garbage content and "rendering for the first time" message on blank pages

Status: RESOLVED FIXED

(developer.mozilla.org Graveyard :: Editing, defect)

Description

[Les Orchard [:lorchard]]

Some pages are blank, migrated as-is from MindTouch.

However, when viewed on Kuma, these pages have garbage content like:
    T�K�j�+��kz���ݜ�����\y�4w޶�����{�[���w-4

And when a logged in user hits shift-refresh to trigger a re-render, this message appears:
    "This document is being rendered for the first time by the system."

But, the "first time" message never goes away, because it's triggered by blank content in the rendered_html database field. The thing is, though, the content is *really* blank, so this message is erroneous.
