title: User with custom role cannot access custom menu item in Magento admin interface
body: <p>I've defined a custom menu item for the Magento admin interface with several sub items. </p>
  
  <p>This works quite well as expected when a user with an admin role is logged into the admin interface. The admin sees all the sub items and can also access the pages the items link to. Each of these pages shows the content of a database table in a grid. </p>
  
  <p>But the problems occur when I try to use a custom role. The custom role has access to the menu item and its sub items. Now, when I log into the admin interface with an user with this custom role the user sees all the menu items as expected, but for two sub items the user gets an access denied message when he clicks on the sub item. </p>
  
  <p>Here is the acl and menu entry from the config.xml. </p>

  <p>The problem occurs for the menu items minimum_order_value and key_value_store. </p>
  
  <p>I don't understand why an admin can access all pages but a different role can not. 
  Any ideas what might the problem here? </p>
