New submission from Steffen Daode Nurpmeso <sdao...@googlemail.com>:
Hello, David, the error from Issue 11116 occurred again,
and it still can be healed with the patch file20675.
(I'm opening a new issue because 11116 turned over to
the mailbox fix.
My repo and installation is at:

Exception: IndexError: list index out of range
In the meanwhile the thing has dispatched tens of thousands
of mails, and no error did ever occur (reading from MBox,
storing as Maildir). This happened when saving the first
message read from a Maildir mailbox to a MBox one.
I think i'll gonna do some round-trip tests tomorrow and
monday evening+. Anyway, patching in file20675 heals the
problem and the thing finishs gracefully.
