Comment:
It looks like the error is caused by an {{{AttributeError}}} raised while
accessing property {{{SimpleTemplateReponse.rendered_content}}} from with
{{{super(...).__getattr__}}} call. In this case any internal
{{{AttributeError}}} is indistinguishable from the one of absence of the
{{{__getattr__}}} itself.
I've reimplemented the code using {{{__getattribute__}}} that doesn't
introduce this side-effect.
I'm in doubts about tests… Should we really test such a strange corner
case and if yes, how? It seems that the only way is to check for certain
words in an exception message which seems fragile.
