I'm making this tracker for language selection problems in anaconda, to summarize what's still broken.
bug 149688: LANG in /etc/sysconfig/i18n is not set
bug 155107: language support packages are not installed
bug 151837: buttons disappearing after language selection screen - maybe not really related to the language selection changes
bug 155840: RFE: always do text mode language selection bug 155847: SUPPORTED languages not correctly set
