Some bugs with the localisation (French), i've got lot of errors with the notification field (heal pet, gain energie, etc...)
What do you mean by bugs? You got error-messages or just some missing localisations?
I just switched my client to german and it worked just fine...
just that the damage-messages show as "(Pet) -123" and the parries show as "Begleiter parieren!" (german for "Pet parry!").
pet-heals and mana gains weren't a problem at all (playing a warlock, didn't test with hunter)
When on my hunter and i feed my pet it shows up as +35 Unknown instead of +35 Happiness
