Well, that quite unfair to my module.
My module *does not* add any rich snippet metadata to miniature list. So, obviously, any error that google shows will be displayed regardless of my module. If you uninstall it, google will still complain about missing aggregateRatings metadata.
Revws module could emit this metadata when it renders stars in miniatures. But then again, this would not fix your problem. Google would still complain about any miniature for product *without* reviews. We can't emit reviews information if no reviews were submitted yet.
The proper course of action for this problem is to remove the Product metadata from miniaures completely. Or just ignore these google warnings...
