Bug #2931
Updated by Tom Clegg over 10 years ago
Under the following conditions
* A link exists in the database with @head_uuid=null and link_class<>'permission'@, owned by (say) admin
* Non-admin user creates an ApiClientAuthorization (e.g., with the "share" button on the Workbench "show collection" page)
* Non-admin user deletes the ApiClientAuthorization (e.g., "unshare")
Result: Permission denied. "dependent: destroy" hook tries to delete all links with head_uuid=null.
