Error on Company List

Hi,

I am on ERPNext v8 develop.

I received the following error when accessing Company DocType.

Traceback (most recent call last):
  File "/home/ubuntu/frappe-bench/apps/frappe/frappe/app.py", line 57, in application
    response = frappe.handler.handle()
  File "/home/ubuntu/frappe-bench/apps/frappe/frappe/handler.py", line 22, in handle
    data = execute_cmd(cmd)
  File "/home/ubuntu/frappe-bench/apps/frappe/frappe/handler.py", line 53, in execute_cmd
    return frappe.call(method, **frappe.form_dict)

    return parser.parse(string_date).date()

    ret = default.replace(**repl)
ValueError: day is out of range for month

Can you please raise a github issue for this?
