Method `configurator_apply()` may create new attachments that will have the same `key` and `website_id` as standard, default images: https://github.com/odoo/odoo/blob/f80094f43bcc464cc99fba6aa59f64659fe659b6/addons/website/models/website.py#L737-L752

Standard images should be updated from the source of the `website` module, but those created by the configurator will have their binary content stored in the filestore and therefore have no need to be updated.

As of right now however, we don't make this distinction when updating `website` data, the following line:
https://github.com/odoo/odoo/blob/f80094f43bcc464cc99fba6aa59f64659fe659b6/addons/website/models/ir_module_module.py#L162

will return both the standard attachment and the one originating from the configurator (due to the same `key` and `website_id`). 
The fix is to tighten the `search` by filtering out records that have `store_fname` set.

This issue was discovered in many databases when upgrading to `saas~17.2` and a few also had this problem when upgrading to  `17.0`. Here is an example traceback from one of the request:
