I try to add norwegian (NO, nb_NO). At the second try it appeared in the list of languages, but when I tried to enable it, I got the message "Language is already enabled or invalid!" and it disappeared from the list.
Debugging information shows that norwegian (NO) is missing in some of the arrays, but not all.:
