I have this issue when trying to remove a module (created for v6 but installed on v8, installed by a hired programmer) from Odoo.

Here is the error:

Traceback (most recent call last):

How can I remove this module?

Context: This was a module developed for us for v6 and it worked fine.  We installed v8 with a different programmer who I guess tried installing that v6 module which sent an email message alerting that a product had reached its Min Reorder Point.  Now we are unable to remove it.  

I found a post here:https://www.odoo.com/forum/help-1/question/error-when-uninstalling-a-custom-module-that-inherits-from-crm-lead-keyerror-crm-lead-74761

So we tried adding ['base', 'custom'] to depends: but that didnt help.

Any ideas?

First thing to do, test on a backup before ! You can after try to delete ir_model_data and view for this model ... Let us know ...
