Product-Image switch on product detail page dont work

Hi,

on my commerce_kickstart installation with no demo content, the product-image switch on the detail page did not work.

Chrome console said that ".spinner()" is not a function... This error happened because of "Drupal.behaviors.quantityWidgetSpinner“ in the product_ui feature js file.

I found a fix for this! Just add this line to your template.php preprocess_html function:
drupal_add_library('system', 'ui.widget');

Please fix this! :)

Greetings and thx a lot for commerce_kickstart
