Hi,

When you uninstall any module, the models ( objects ) which are in that module, needs to be removed. ( Settings >> Technical >> Database Structure >> Models )

But I have seen sometimes that models not able to delete from here. 

So in order to remove that error, please do following thing.

1) Go to Terminal

2) Open postgres database console.

3) Fire following query,

delete from ir_model where model = 'crm.lead.assignation'

4) Restart OpenERP.

Now that error should be no more.

Feel free to comeback if you still having problem,
