Chose norwegian during install of 5.9.0, upgraded (rpm -Uvh) to 5.9.1. - the menu does not use the translated entry for "Applications" even though it is in /usr/share/gnome/apps/Applications/.directory (Name[no]=Applikasjoner) - gnome-terminal and gnome-help-browser do not use the translated help files unless I comment out "LC_ALL=no_NO" from /etc/sysconfig/i18n. - when commenting out this entry from /etc/sysconfig/i18n the clock applet does not show the translated messages.
These seem to all have been fixed before 6.0.
