Hidden location prevents registry admins from changing a user's LP ID

If a user has hidden his location data then the attempt to change his LP ID by a registry expert will fail since the location information is only visible to the user and LP admins. The failure is:

Module lp.registry.browser.person, line 1749, in change_action
self.updateContextFromData(data)
Module canonical.launchpad.webapp.launchpadform, line 414, in updateContextFromData
context, providing=providedBy(context))
Module lazr.lifecycle.snapshot, line 85, in __init__
value = getattr(ob, name, _marker)
Module lp.registry.model.person, line 612, in latitude
return ProxyFactory(self.location).latitude
Unauthorized: (<PersonLocation at 0x10138e50>, 'latitude', 'launchpad.View')<br />
