foreach() error when there is nothing in the "create content" menu

i had moved the "create content" submenu items to another location, so the "create content" menu item had no children. when i installed admin_menu, it threw the following warning until i gave "create content" a child menu item:

warning: Invalid argument supplied for foreach() in /drupal/sites/all/modules/admin_menu/admin_menu.module on line 201.
