Is this really implemented?

I was using redmine in Italian (IT_it) locale but i was getting this error 500 on administrative user editing pages:

ActionView::Template::Error (can not load translations from /omissis/path/config/locales/*sr-CY.yml*: #<Errno::ENOENT: No such file or directory - /

sr-CY is not a language that I was using in any way!!! And the only web browser that was browsing the redmine instance was mine in IT_it locale.

I removed the sr-CY.yml file and the error fixed, anyway this means that translation is not really lazy loaded (I'm using redmine 2.4.2 and ruby 1.9.3), contrary an error in a unused translation parsing is blocking for the used translation too!

--------------------------------------------------------------------------------
sr-CY.yml was removed by r4003.
--------------------------------------------------------------------------------
I apologize it was my bad, i did a wrong redmine upgrade keeping the old files too!
