Created attachment 1064474 [details] fix the bug (by swiping the _ definition from anaconda) system-config-language runs OK in Python 3 in English, or in Python 2 in any other language, but when running in a non-English language in Python 3 it hangs such that it can't even be ctrl-C'ed (has to be kill'ed from another terminal): root@adam system-config-language (master *%)]# LANGUAGE=de_DE.UTF-8 /usr/share/system-config-language/system-config-language.py Traceback (most recent call last): File "/usr/share/system-config-language/language_gui.py", line 341, in do_activate win = ChildWindow(self) File "/usr/share/system-config-language/language_gui.py", line 41, in __init__ self.title = Gtk.Label.new(_("Language Selection")) TypeError: Must be string, not bytes This can be fixed by swiping anaconda's definition of '_' (the conventional name for the function for 'translate this string'). One of system-config-language's files currently defines it as 'gettext.gettext', which seems to cause the hang. Patch attached. I just stole anaconda's '_' definition. Tested in both py2 and py3. I'll apply this patch in the package spec for now, once it's applied upstream it can be removed from the package.
