Comment 0 for bug 396406

Currently it is possible for a project timelord to mark a public bug as a duplicate of a hidden private bug. For example:

  https://bugs.launchpad.net/ubuntuone-client/+bug/394295

which was marked as a duplicate of:

  https://bugs.launchpad.net/bugs/354502

meaning that the original helpless reporter can end up seeing:

   **Not allowed here***
   Sorry, you don't have permission to access this page.

(until I unduped it to switch the affected projects around and now can't de-dup it---separate issue).

This bug can probably be generalised that two bug reports should have the same privacy status to be allowed as duplicates.
