[New-bugs-announce] [issue10574] email.header.decode_header fails if the string contains multiple directives

[Roy H. Han]

New submission from Roy H. Han <starsareblueandfaraway at gmail.com>:

email.header.decode_header fails for the following message subject:
::

    email.header.decode_header('=?UTF-8?B?MjAxMSBBVVRNIENBTEwgZm9yIE5PTUlO?==?UTF-8?B?QVRJT05TIG9mIFZQIGZvciBNZW1iZXJz?==?UTF-8?B?aGlw?=')


If the directives are removed and the padding problems are fixed, the subject parses correctly.
::

    email.header.decode_header('=?UTF-8?B?%s==?=' % '=?UTF-8?B?MjAxMSBBVVRNIENBTEwgZm9yIE5PTUlO?==?UTF-8?B?QVRJT05TIG9mIFZQIGZvciBNZW1iZXJz?==?UTF-8?B?aGlw?='.replace('=?UTF-8?B?', '').replace('?', '').replace('=', ''))
