as some of you might have seen keyword.URL on
browser/chrome/browser-region/region.properties is no more.
Here you have a rs=me on removing that entry from your versions of
region.properties.
This is only for l10n-central, and, once we have it,
releases/l10n-mozilla-2.0. *Do Not* remove it one
releases/l10n-mozilla-1.9.2 or earlier.
