I **think** I've found the problem.
After some tests, I've deduced that the error is thrown when using DAL with
lazy_tables=True.
So when I retrieve a Row from "contenido" table, the returned object does
not contain the "galeria_contenido" set.
Is this a bug? Or I've been using lazy_tables in the wrong way?
I ask because I've been using this code in production for a while with no
errors, but the error only appeared when I upgrade from 2.10.3 to 2.11.2
(haven't checked intermediate versions).
