[Bug 1317115] Re: KDE Locale module support for changing language is incomplete

[Harald Sitter]

** Description changed:

- The current Kubuntu method of installing support for new languages and
- changing which language gets highest preference is broken because it
- only affects KDE applications. The system language (as set by the LANG
- and LANGUAGE environment variables) isn't changed, and the language
- support for added languages is incomplete - for example missing
- localisation packages for Firefox, Libreoffice and spell checkers, among
- others.
+ [Impact] 
+ Language configuration will not write the necessary envrionment setup files to make non kde applications localized unless it is switched into debug mode. This was fixed by moving the related write function call out of the noop kdebug statement to make sure that it is executed regardless of whether the kdebug is turned noop.
+ 
+ [Test Case]
+ 
+ * delete .kde/env/setlocale.sh
+ * run kdebugdialog
+ * deselect everything
+ * run kcmshell4 language
+ * change a language setting
+ * apply changes
+ * make sure .kde/env/setlocale.sh was generated again with the configured settings
+ 
+ [Regression Potential] 
+ none
+ 
+ [Other Info]
+ n/a

  This is a side-effect of the deprecation of the language-selector-kde
  package, which used to give Kubuntu users the same fuctionality as
  gnome-language-selector by creating an extra module in KDE System
  Settings.
  
  The missing functionality should be integrated into the KDE System
  Settings Locale control module, as mentioned in this comment
  https://bugs.launchpad.net/ubuntu/+source/language-
  selector/+bug/1013626/comments/4
  
  To reproduce:
  1. Freshly installed Kubuntu 14.04 system. KDE System Settings->Locale->Language.
  2. Add language (in my example German). Wait while Locale module installs the necessary packages.
  3. Move language (German) to top of the priority list, above the default American English
  4. Logout of KDE, log back in
  
  Expected Results:
  All necessary language files for both KDE applications (e.g. Dolphin) and non-KDE applications (e.g. Firefox, Libreoffice) is installed. All programs which have German translations available display in German. Environment variables are set so that command line programs also run in German (where translations available), eg:
  tim at localhost:~$ ls notthere
  ls: Zugriff auf notthere nicht möglich: Datei oder Verzeichnis nicht gefunden
  
  In short - the same effect you'd get by using gnome-language-selector
  
  Actual Results:
  Only the language of KDE applications is changed. Firefox, LIbreoffice, command line programs, bash environment vars, and all other programs remain in English. In other words you have a half-half system as far as language support is concerned.
  
  Workaround:
  sudo apt-get install gnome-language-selector
  gnome-language-selector
