oEmbed and Kickstarter

So I’ve been trying to register Kickstarter with the wp_oembed_add_provider function and for some reason it doesn’t work for me.

Here’s and example calling kickstarter’s oembed provider URL:
https://www.kickstarter.com/services/oembed?url=https://www.kickstarter.com/projects/crypteks/crypteks-usbtm-encrypted-and-lockable-usb-solution

Here’s the code I added to functions.php

add_action( 'init', 'add_oembed_providers' );
function add_oembed_providers() {
    wp_oembed_add_provider( 'https://www.kickstarter.com/projects*', 'https://www.kickstarter.com/services/oembed', false );
}

I’ve added other oembed providers with no problem, and Kickstarter’s oembed output looks like well-formed JSON, but wordpress just doesn’t display the video embed no matter what.

Any ideas?
