Erreur de gonflement des fragments lors des changements d'orientation

Question

Ok, voici le problème, j'ai une activité fragmentée qui contient deux fragments. L'un est un ListFragment et l'autre un Fragment. Je veux donc afficher le fragment en fonction de l'élément sélectionné. Voici le problème. Si je lance cette activité de fragment soit en mode paysage, soit en mode portrait, elle fonctionne bien. Cependant, lorsque je passe à l'autre orientation, elle se bloque toujours. L'erreur concerne l'inflateur, quelque chose comme le onCreateView mais j'ai regardé dans d'autres articles et aucune des autres résolutions telles que onConfigurationChanges, onSaveInstances, le changement de nom en classe. Toutes ont la même erreur. J'espère donc que quelqu'un pourra m'aider. J'ai bien le layout-land et le layout et ça ne marche toujours pas.

Voici mes codes.

activité_pontix (en mode terrestre et portrait)
