UserApp v. 3.5.1, private support patch N

In attempting to limit what the average user sees, I set the permissions to
"View Permissions Set To Admin Only" on those shared pages that I don't want

This succeeds in hiding a variety of pages (Password Sync Status, Password
Hint Change, My Profile) but when I try to hide the Organizational Chart, I
get the following error:

"Access denied to the portal page: MyOrgChart!"

Seems like a bug, since the hiding works on so many other pages, and I've
been able to replicate this across tow different installs. Anyone else see
this? Or is this a special case and I'm missing a configuration setting?
