How to reproduce the issue?

Refreshing the URL occasionally returns the 404 page in an unexpected language.

Line 12 in acd899d

before_action :lookup_user, :only => [:index]

Screenshot(s) or anything else?

Page unexpectedly in German:

We probably need to review all the lookup_user calls and make sure they come after set_locale and probably web_timeout as well though that's unlikely to matter much.

It's not really related at all though other than in the most tangential way.
