Is it possible for you to attach your db schema and/or the code that triggered this?

[areski]

Sure, here you go http://pastebin.com/AmqVNdw5
and I trigger it like this : sandmanctl postgresql://postgres:password@localhost:5432/newfiesdb

I'm unable to reproduce this (by adding a record to 'southmigration_history', for example). What was the specific value you were trying to use and on which model?

[areski]

for instance if I try to update a record in dnc_contact : http://localhost:5000/admin/dnc_contactview/edit/?url=%2Fadmin%2Fdnc_contactview%2F&id=3

then I will get the following error http://pastebin.com/NixuUWfY

I've got the same error. Is there a solution?
