--- Comment #1 from Parag Nemade pnemade@redhat.com --- Sorry unable to reproduce above traceback. Maybe provide more details like what you did? On fedora 23, you just start "system-config-language" as normal user from gnome-terminal??
What was your locale set when you ran "system-config-language"?
