My bad, didn't see property_account_income_categ_id in the subject. What's actually the back story to this? What have you done prior to this error? Upgraded database? What version are you running?

I am not sure how it started.. 

I have a database with several companies, and for some reason I cannot get into "Settings" when I click on it I get the message above.
