unsupported operand type(s) for +: 'NoneType' and 'bytes'

[tanguy-a]

Describe the bug Error raised by the lib textract in /textract/parsers/msg_parser.py l.27 when the "m.subject" is empty.

def extract(self, filename, **kwargs): m = extract_msg.Message(filename) return ensure_bytes(m.subject) + six.b('\n\n') + ensure_bytes(m.body)

When returning it tries to concatenate an empty string (subject)

To Reproduce Steps to reproduce the behavior: Use process on a .msg file which doesn't have a subject.

Expected behavior I'd still like to get the text processed by textract even tho the subject is empty.

Desktop (please complete the following information):

• OS: MacOS Catalina
• Textract version 1.6.3
• Python version 3.7.7
• Virtual environment no

Thank you for your help.
