Comment 1 for bug 487402

Error = Programming error: field 'def_rec_acc' does not exist in object 'res.partner.bank' !
Are you sure it is a bug you did log? Because this is a variable that seems not filled. This variable contains the default receivable account defined for your company and that one seems empty.
I can not reproduce this in my environment. Please check you company setup and general ledger setup. Normally these accounts (account receivable and account payable) are defined within your chart module.
