Comment (by andrew.mathas):

 Hi Anne,

 I have discovered the register_unpickle_override function. Using this I
 have eliminated all but the following four unpickling errors:

     *
 
_class__sage_combinat_crystals_affine_AffineCrystalFromClassicalAndPromotion_with_category_element_class__.sobj
     *
 
_class__sage_combinat_crystals_tensor_product_CrystalOfTableaux_with_category_element_class__.sobj
     *
 
_class__sage_combinat_crystals_tensor_product_TensorProductOfCrystalsWithGenerators_with_category__.sobj
     * _class__sage_combinat_tableau_Tableau_class__.sobj

 These error are, I think, all due to the fact that the old Tableau_class
 has been replaced with the quite different Tableau class. My guess is that
 the only way to fix these unpicking errors is to update the pickle jar. Is
 this right? If so, then it probably is not worthwhile including all of the
 register_unpickle_override statements that I have just inserted. Let me
 know what you think.

 I will upload a patch which fixes the docbuild problem that you mentioned,
 together with a few typos in the documentation and most of the unpickling
 problems, but I will hold off deprecation and the four problems above
 until I hear from you.

 Best,

 Andrew
