I was getting the following traceback when an error occurs in a validator in
my siteamostras.materiais module:

The problem is that I was using tg_errors attribute syntax in this module but
the decorator syntax in my siteamostras.equipamentos module. If I mix
decorator + attribute syntax even in different modules, this happens. I've
switched all my code to use the attribute syntax since I can have a better
control here.
I believe there's some 'leak' or something that isn't safe happening that is
mixing error handlers.
