12019	Corsican appears in the blogs language drop down box	wpmuguru	nbachiyski	"MU Trac Ticket: http://trac.mu.wordpress.org/ticket/1109

In the last version, support for translation was added to the time zone list of cities. Since it is a long list, and should be loaded only when the 'General Settings' page is loaded, it uses a separate translation file (continents-cities). The list of cities is here:  http://trac.mu.wordpress.org/browser/tags/2.8.4a/wp-admin/includes/continents-cities.php

Since I'm using the Hebrew translation I have two .mo files in my languages directory: he_IL.mo and continents-cities-he_IL.mo. Wpmu searchs for all *.mo files and checks the first two letters of the file name to determine the language. According to this, the continents-cities-he_IL.mo file is recognized as Corsican.

This issue appears in options-general.php and for admin also in wpmu-options.php.

As far as I know, all translations use a file name structure of 'aa_bb.mo' where 'aa' is the language and 'bb' is the country. A possible solution to this issue would be to check for the underscore ('_') after the first two letters of the file name to make sure it’s a different language.
