[SmartCrawl Pro] SmartCrawl Pro v. 2.2.2.4 problems with Formidable and other Plugins

I've got a problem while using the current version of the mentioned Plugin.
Old working code in core.php (on line 359):
$string = trim( preg_replace( '/\r|\n/', ' ', strip_shortcodes( htmlspecialchars( wp_strip_all_tags( strip_shortcodes( $string ) ), ENT_QUOTES ) ) ) );

New code which causes ob_start() errors in various other Plugins:
$string = trim( preg_replace( '/\r|\n/', ' ', strip_shortcodes( htmlspecialchars( wp_strip_all_tags( do_shortcode( $string ) ), ENT_QUOTES ) ) ) );
Changing that line back to v. 2.2.2.1 of the plugin resolves the problem.

Hopefully you understand my problem
