When faced with an error like this:

  File "/opt/openerp/server/openerp/netsvc.py", line 293, in dispatch_rpc
    result = ExportService.getService(service_name).dispatch(method, params)
  File "/opt/openerp/server/openerp/service/web_services.py", line 626, in dispatch
    res = fn(db, uid, *params)
  File "/opt/openerp/server/openerp/osv/osv.py", line 188, in execute_kw
    return self.execute(db, uid, obj, method, *args, **kw or {})
  File "/opt/openerp/server/openerp/osv/osv.py", line 144, in wrapper
    raise except_osv(inst.name, inst.value)
except_osv: ('ValidateError', u'Error occurred while validating the field(s) arch: Invalid XML for View Architecture!')

How do I find the exact line of code that is throwing this error? I know that people here might try to help me debug my code if i post it here, but how can I do it myself?
