I verified the test case using version 0.6.55-0ubuntu12~20.04.2 of accountsservice, gir1.2-accountsservice-1.0 and libaccountsservice0 from focal-proposed.

It leads to incorrect behavior under certain conditions and also a crash if the function was triggered from language-selector-gnome. Even if this only makes a difference in special corner cases, it happens often enough to justify this SRU: https://errors.ubuntu.com/?release=Ubuntu%2020.04&package=language- selector&period=year (It's the top ranked crash type in the list.) The version in focal-proposed fixes the issue. [Test case] Make a fresh install of Ubuntu 20.04 (a VM works fine) Once logged in: * Install accountsservice, gir1.2-accountsservice-1.0 and libaccountsservice0 from focal-proposed * Open /etc/default/locale for editing, replace its contents with the single line: LANG=C.UTF-8 and reboot. Open Language Support and change language (drag any language above the "English" item) Open ~/.pam_environment and find that e.g. LANG is now the locale representing the language you selected, while e.g. LC_TIME is set to "C.UTF-8". [Regression risk] This is a oneliner which white list "C.UTF-8" as a valid locale name. I can't think of a case where this would cause unexpected behavior.
