During uninstallation of a module, recompute operations may be triggered.
The prefetch might thus try to read a column that has already been deleted.

Install CRM, create an opportunity then schedule a meeting
(itself a calendar event linked to the opportunity).
Note that the CRM module adds an opportunity_id field on events.
When you try to uninstall the module, the bug is triggered.
The calendar model contains a res_model field, which is related to res_model_id.
Its recompute triggers the prefetching of the opportunity_id field,
which has already been removed.
