New submission from Tim Koopman <python....@nandoe.net>:
Creating an empty header produces an exception when calling the encode function:
>>> from email.header import Header
>>> Header('', 'iso-8859-1').encode()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python3.2/email/header.py", line 317, in encode
formatter.feed(lines[0], charset)
IndexError: list index out of range
According to RFC822, empty headers are valid (and are found in the wild
anyway), so this should just work.
I've attached a trivial fix that appears to work.
