If you use a different Login plug-in (for instance HttpAuthLogin), you'll notice that the "logout" link on the frontpage doesn't call the new plug-in, but still calls the old (default) Login plug-in
Technically, we should point the logout to the appropriate plugin; that said, logging out of HttpAuth is non-trivial. (e.g., http://www.nanodocumet.com/?p=6 )
it's the same for feedback, dashboard, api, ... -> all are hardcoded ... :(, if seen this after deeactivating the feedbackplugin

(In [1131]) fixed #551 - "Logout" / "Sign out" action linked to the active
authentication plugin.
