Hi. After remove some blog tags, now I see in the log a lot of errors like this:

Traceback (most recent call last):
  File "/home/od/odoo/odoo/fields.py", line 1049, in __get__
    raise MissingError("\n".join([
odoo.exceptions.MissingError: ('El registro no existe o ha sido eliminado.
n(Registro: blog.tag(50,), Usuario: 26570)', None)

I'm using Website Blog Search for tags management and searches into the blog. I can see it gets the current tags and make a browse for them. But I see it find the removed tag and then, when it tries to access to some attribute, then it fails.

Why odoo can access to this removed tags? How can I solve this?
