Need fix to work with woocommerce

Hey
with woocommerce activated, I've got this error:

Warning: Invalid argument supplied for foreach() in \wp-content\plugins\woocommerce\includes\class-wc-webhook.php on line 89

10 0.3567 71698984 WC_Webhook->enqueue( ) ..\woocommerce.php:574

When I deactivate babble, the warning disappears. It displays both front and back

WordPress 4.0 / Woocommerce 2.2.8 / Woocommerce subscriptions 1.5.12

Start by reproducing the warning with WordPress 4.0, WooCommerce 2.2.8, and Babble active, then trace WooCommerce->init(), WooCommerce->load_webhooks(), and WC_Webhook->enqueue(). Inspect woocommerce/includes/class-wc-webhook.php at line 89 and the Babble integration involved in webhook loading. Done means the warning no longer appears in either the front end or admin while WooCommerce remains active.
