I'm getting various errors related to google_drive, so I've attempted to uninstall any/all Google-related modules. They were never configured. I clicked the uninstall buttons for modules google_base_account and google_drive. When I select Settings -> Modules -> Apply Scheduled Upgrades I receive confirmation that the modules will be removed. However, when I click the Update button, this is what I get:

OpenERP Server Error

And the modules are never uninstalled. Note that this is in v8... :)
