Hi,

The administrator notice (Custom breadcrumbs have been created for ... . Use the Custom Breadcrumbs Administration Page to add additional breadcrumbs, or follow the links in the table below to edit or delete existing custom breadcrumbs.) is visible on taxonomy term edit pages for users that don't have permission to administer Custom breadcrumbs.

How to reproduce:

  1. Give user other than admin the permission to edit certain taxonomy.
  2. Add custom breadcrumbs for said taxonomy.
  3. The administrator notice will be visible for that user when editing a taxonomy term.

Cheers
