+localechooser (2.39ubuntu2) precise; urgency=low

+  * Invert the set of locale categories set in case of a language/location
+    conflict, so we now set LC_NUMERIC, LC_TIME, LC_MONETARY, LC_PAPER,
+    LC_NAME, LC_ADDRESS, LC_TELEPHONE, LC_MEASUREMENT, and LC_IDENTIFICATION
+    instead (LP: #926207).
