Disable breadcrumb on View in Drupal Commerce Kickstart
Do you want to disable the breadcrumbs entirely? If so, with kickstart, you can do so at:

Appearance > Settings > Commerce Kickstart Theme > Toggle advanced elements

It looks like commerce kickstart 2 uses the crumbs module (https://drupal.org/project/crumbs) to handle breadcrumbs (that's what I see in a local install from late July).

I haven't worked with Crumbs, but the documentation is here: https://drupal.org/node/1004394
