Subject: [PATCH] ULS LCD: Check if region exists before adding languages

The regions displayed on ULS depend on the showRegions parameter
passed to uls.lcd plugin. If a new language and region have
been added to the language data, the region for it will not be
available to showRegion because it's static.
