Thanks for your detailed analysis. It was helpful to know all the things that can nowadays alter ones /etc/nsswitch.conf and change the behavior in surprising ways.
There is no "wontfix" state in launchpad, so I will mark this as "invalid" since it was caused by a local configuration issue. Still, as you said, there is useful information in this bug, and we can always reopen it if other scenarios where this could happen show up.
