Subject: [PATCH] Move default_pref from data/ to config/ dir. We will check
 the legacy locations first in order to remain backwards compatible (an
 upgrade will still use the old location but a new install will use the new).
 When not found, do not exit with an error, just create an empty prefs file.
 Fix the title of the error message.
