My system language is German but my text in libreoffice writer gets all underlined because the spell chechking language is set to English USA. Neither can I change it to German there which is also listed nor can I change it via Extras --> Language --> All text.
I deleted two folders named "bundled" and restarted libreoffice but the problem persists. No new folders called bundled created by the way.
I've also installed a German dictionary via extensions which didn't help.
I'm on 12.04, system is up to date.
