[QGIS-Developer] Locale in settings

[Nicolas Godet]

Dear devs,

Before raising a bug (if it's really a bug), I was wondering why the `userLocale` in QgsSettings is stored using a short string, eg. `fr` for french instead of `fr_FR` ?
`globaleLocale` is OK with `fr_FR` for french.

Seconde question
I tried, using a .ini file with QGIS_GLOBAL_SETTINGS_FILE env var, to force locale settings when creating a new profile.
Plugins complains because the setting `userLocale` is not defined.

.ini file :
[locale]
userLocale=fr
overrideFlag=true
globalLocale=fr_FR
showGroupSeparator=false

When QGIS starts, Python error:
QSettings().value("locale/userLocale")[0:2]
NoneType is not scriptable.

And in Python console, if I execute the above command, the return is empty but in settings, the setting `locale/userLocale` is set to `fr`.

Regards,
Nicolas
