[FIX] mail: when creating a new object from incoming mail, don't call default_get before the call to super(). The create method from the orm is adding default missing value itself. It is also the cause of a bug on stage selection because custom code in create() is not run when stage_id is given in vals (and it's filled here by default_get() but return a wrong value as context cannot be used from incomming mail).
