Nevermind, I was wrong, I was able to reproduce it:

>>> msg = email.message_from_string('To: (Recipient list suppressed)', policy=email.policy.default))
  File "<stdin>", line 1
SyntaxError: unmatched ')'
>>> msg = email.message_from_string('To: (Recipient list suppressed)', policy=email.policy.default)
>>> msg.get('to')
Traceback (most recent call last):
