<h3>Log Message</h3>
<pre>Remove WP_FALLBACK_THEME, use WP_DEFAULT_THEME instead. We now only fall back to the default theme if the theme is broken. Incomplete themes that need to inherit templates will inherit them from wp-includes/theme-compat -- this behavior is deprecated. fixes <a href="http://trac.wordpress.org/ticket/12846">#12846</a>.</pre>
