function wp_nonce_meta_refresh($action = -1, $name = "_wpnonce", $referer = true) {
	$name = attribute_escape($name);
	echo '<meta http-equiv="refresh" content="0;admin.php?import=flatimport&step=3&'.$name.'='.wp_create_nonce($action).'">';
	if ( $referer )
		wp_referer_field();
}

Replacing echo ‘<meta http-equiv=”refresh” content=”0″>’;

by wp_nonce_meta_refresh(‘import-flatimport’); do the meta refresh.

It will be appreciate if a dev can comment on this function.

the flatimport.php importer is available here:
Flat Import

there is also an improved version of the dotclear.php importer.

Hope this help!
