Actually I think it would help. The moment that currently fails is accountsservice's writing to its keyfile and ~/.pam_environment. So now, when you just have installed a new language, and wants to use a locale of that language for regional formats, you first need to log out/login to be able to accomplish the writing, and then log out/login again to make the new setting part of the actual environment.

I checked the glibc source code, and it's not currently possible to reload locale-archive from a running program. So we do need to call out to locale -a.

The proposed change in accountsservice should fix this bug.

However, the example box on the "Regional formats" tab in language-selector depends on locale.setlocale() in Python, and neither that function has access to just generated locales, so the box shows an error message (se attachment). OTOH, the locale is set properly, and the program does not crash. Also, if you close language-selector and re-open it, the example box is filled as expected.

With the proposed change to language-selector, the error message on the screenshot would instead read:

  [ Failed to apply the 'fr_FR.UTF-8' format
  choice. The examples may show up if you
  close and re-open Language Support. ]
