Comment 2 for bug 809043

James, your explanation for why this report is invalid just restated my bug description.

The bug precisely is that Ubuntu is shipping a package (upstart's bash completion) with an implicit dependency on another package (dbus) that it does not declare! So if the developers view this dependency as optional, then the upstart package should: 1) declare dbus as suggested; and 2) not throw an error in the completion function if dbus is not running but fail gracefully and degrade to not completing anything instead of dumping errors to console.
