Description:
------------
Fairly fresh 16.04 Ubuntu install. I was once able to change my system language
between English, French, Esperanto and Japanese. Now I am unable to change to
any of them. I have been troubleshooting the issue. Things that I have tried:
1) Creating a new user. Also fails.
2) Purging and reinstalling language-selector-gnome and language-selector-common
3) Purging and reinstalling language-selector-gnome, language-selector-common,
fontconfig and fontconfig-config
4) Purging language-selector-gnome, language-selector-common, fontconfig,
fontconfig-config and all japanese language packs
5) Removing all language packs from Language Support GUI (aka
language-selector-gnome)
I am now looking into the problem itself. When running the Language
Support GUI manually from the terminal via python3 /usr/bin/gnome-
language-selector I get the following error:
-----------------------------------

-----------------------------------
I have also taken a strace of this as well via strace -F -tt -s 255 -o
ls.strace python3 /usr/bin/gnome-language-selector and will attach it to
this issue as well as my current dpkg.
