I just poked around in my settings, and just noticed that under the language I got an error message saying "Translation files for the language 'sv' couldn't be found...", also if I try adding English I got the error "There's no language avalible in the system".
I can't find any localization files to install in Octopi, except for Firefox and Thunderbird. Allthough, everything seems to work, my system is in Swedish. Any idea what could have happend?
