Change of “home” results in timeouts (only on index.php)

I fixed it. This behaviour was due to a redirect loop from “home” to “home”.

Adding the following line to wp-setting.php dit it for me. Sadly this is only a workaround. Maybe someone can hint me to a better fix.
remove_action(‘template_redirect’, ‘redirect_canonical’);
