The method getThumbUrl() does not exist on null.

    }

        if ($this->thumbnailModel == null) {
            $this->thumbnailModel = OwnerMediafile::getOwnerThumbnail($this->tableName(), $this->id);

It seems like tableName() must be provided by classes using this trait. How about adding it as abstract method to this trait?

        }

        return $this->thumbnailModel;
    }
