How to redirect views of entity types (bean) for user roles?
From quick view of RabbitHole I would suspect that it doesnt support blocks. One way to prevent this could be to use hook_block_view_alter and drop the data when comparing the url. Something like

function MYMODULE_block_view_alter(&amp;$data, $block) {
  // Remove the data if some page view, possibly
  // this would also disable the data on bean/123/delete... :/
  // mayby instead dpm($block) with devel for better targeting? 
  if (arg(0)=='bean' &amp;&amp; arg(2) !='edit') {
    unset($data['content']);
    //or redirect
    //drupal_goto('somepage');
  }
}
