Hi Darij, I get the same error that you get in sage-5.4 and sage-5.5.rc0 with the entire sage-combinat queue applied, both the sage.structure.coerce_dict.TripleDictEraser ValueError and the problem with StandardTableaux(3).list().
When you remove the sage-combinat patches, the error disappears, so I suggest you just do from your /sage-5.4.1/devel/sage-combinat directory sage -hg qpop -a sage -br and everything should work for you! Who is making changes to tableaux in the sage-combinat queue? Travis? Andrew? Perhaps you should check your code!
