Yes, I got it !
So I changed the "Tasks" default name to "Taches". It seems to work 
since I created a new user and can see the "Taches" folder in Cyrus with 
the correct "folder-type: task.default" annotation.
But, now, when I try to add a new task, I receive this message :
"No message corresponds to object 0" (In french : "aucun message ne 
correspond au sujet 0").
Any idea of what is going wrong ?

Thanks,
