** Description changed:
+ [Impact]
+
+ accountsservice includes a function for checking the validity of
+ locales, and it incorrectly considers "C.UTF-8" to be invalid. 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.
+
+ [Original description]
