I'm using Python 2.7.3rc2 from debian sid packages.
If a mailbox.Maildir object is created with a unicode dirname,
retrieving a message tagged with maildir flags with get() or get_message() fails with the following exception:
Traceback (most recent call last):
 File "reproduce.py", line 21, in <module>
 mb.get_message(key)
 File "/usr/lib/python2.7/mailbox.py", line 343, in get_message
 msg.set_info(name.split(self.colon)[-1])
 File "/usr/lib/python2.7/mailbox.py", line 1480, in set_info
 raise TypeError('info must be a string: %s' % type(info))
TypeError: info must be a string: <type 'unicode'>
Since python os.path module seems to cope with unicode paths http://docs.python.org/howto/unicode.html, it would be nice to fix this issue.
Attached is a simple script reproducing the bug.
The following patch seems to solve the issue for me:
