I'm not quite sure what it's complaining about. There's only a /!\ triangle after some languages, without further explanation. Sometimes those were missing from LINGUAS, but often they've been in LINGUAS for eternities, so I have no idea what's wrong with those languages.
If problems persist, please file new bugs in bugzilla.gnome.org, thanks!
Thanks Tim, remaining warnings are minor problems that should be fixed by translation teams.
