I think this is a duplicate of Bug #36145 which is due to a the contents of "/etc/texmf/language.d/10tetex.cnf" not being included in "/var/lib/texmf/tex/generic/config/language.dat". The fix presented in Julien's second post on the page for Bug #36145 fixed everything for me (using any lagnauge - i've tried British (downloaded), US English, French and Danish language options so far).
