Removing the rewriting the header tag during the import.
This caused not only text to disappear but in combination with 'nikola build' two rewrites of the header tag were made. If the source had an header of h1 this would be a h3 after the build. Now it is only a h2 (the h1 is still reserved for the title of the post/page).
