[web2py] Bug in post-1.79.2 versions

[Jose]

Since post-1.79.2 versions introduced a bug regarding the fields
'upload'.

Given the following application:

Model:

db.define_table('mitabla',
    Field('nombre'),
    Field('archivo', 'upload', autodelete=True,),
)

Controller:

def subirarchivo():
    form = crud.create(db.mitabla)
    registros = db(db.mitabla.id>0).select()
    return dict(form=form, registros=registros)

def editararchivo():
    form = crud.update(db.mitabla, request.args[0])

    return dict(form=form)

View (subirarchivo):

{{=form}}

<ul>
{{for r in registros:}}
    <li>{{=r.id}} | {{=r.nombre}} {{=A('[editar]',
_href=URL(r=request, f='editararchivo', args=[r.id]))}}</li></li>
{{pass}}
</ul>

When I edit a record I get the following error:

Traceback (most recent call last):
