This patch wouldn't compile.

 }

This one fixes the problem.. InitLocale? needs the database to be configured and up and running as it retrieves the configured locale from the database. However, the issue at hand is when trying to display the screen for setting up the locale and the database. So we can't use InitLocale? yet.
