Not sure if this will create the problem you describe, but I believe
(and I could be wrong) that the 'verbose_name' argument is only used
for ForeignKey, ManaytoMany, and OnetoOne fields (because the first
argument must be a model class).  I think that your descripcion field
should look like this:

descripcion  =  models.CharField("descripción", max_length = 50, blank
= True)

Mind you, I am pretty new to Django, so  don't take this as
authoritative.
