Answer 1

Tive o mesmo problema, a partir de uma rápida olhada, vi que o código estava entrando nessa parte para determinar o idioma e apenas quando 'SERVER_MODE' foi definido como False. Eu removi a linha da configuração e funciona. Tenho certeza de que existe uma solução melhor, mas isso pode ajudar nesse meio tempo.
