Comment 5 for bug 397188

This design feature obviously leads to problems for security related bug attachments ;)

Seems that we should

- describe more clearly that simply removing a bug attachment does not automatically delete the Librarian file

- add an option to reliably delete the librarian file of a bug attachment. Such an option should probably only available to people with sufficient privileges, like a project owner or a driver.

A form allowing the latter should display something like:

  This file is also referenced as
  * a bug attachment of bug 1234
  * a logo for projext X
  * ....
  are you sure that you want to completely delete this file?

(OK, having a librarian file both as a bug attachment and as a logo is not very likely, but Launchpad references LFAs from 43 different tables; I can't come up quickly with a better example...)
