Package: offlineimap
Version: 6.0.0
Severity: important
OfflineIMAP crashes with the following messages:

followed by a whole bunch of messages (I presume 50) which appear to
be in groups of four. The last grouping is:
imap: imapsplit() called with input: FLAGS (\Seen) UID 4799
INTERNALDATE "19-Jan-2038 11:14:07 -0800"
imap: imapsplit() returning: ['FLAGS', '(\\Seen)', 'UID',
'4799', 'INTERNALDATE', '"19-Jan-2038 11:14:07 -0800"']
imap: options2hash called with input: ['FLAGS', '(\\Seen)',
'UID', '4799', 'INTERNALDATE', '"19-Jan-2038 11:14:07 -0800"']
imap: options2hash returning: {'INTERNALDATE': '"19-Jan-2038
11:14:07 -0800"', 'FLAGS': '(\\Seen)', 'UID': '4799'}
This first manifested after a system upgrade from stable, so I believe
that the version of both OfflineIMAP and python have changed. If I
understand the messages, it is crashing because a message on the IMAP
server (an exchange server) has an invalid date.
The first time I hit this message, it was for a local message which
did, in fact, have an invalid date, so I removed that file. Then it
hit another file, so I nuked all the files and metadata and did a full
redownload. This worked swimmingly for thousands of messages until
the message above. The local copy of that folder is empty, so I know
it's an issue with the message on the server, not in the local file
system. I tried to use a different IMAP client to find the message in
question, but none of the visible date fields seemed to correspond. I
suspect that means that it's server meta data or something, but I
don't really know.

We're not talking about the Date: header in a mail. This is an internal
date stored by your IMAP server. Usually it is a timestamp of when the
IMAP server first processed a message, though if memory serves, this is
a bit vague.
Actually, indeed it is both vague and specific, heh. from RFC3501:
2.3.3. Internal Date Message Attribute
The internal date and time of the message on the server. This
is not the date and time in the [RFC-2822] header, but rather a
date and time which reflects when the message was received. In
the case of messages delivered via [SMTP], this SHOULD be the
date and time of final delivery of the message as defined by
[SMTP]. In the case of messages delivered by the IMAP4rev1 COPY
command, this SHOULD be the internal date and time of the source
message. In the case of messages delivered by the IMAP4rev1
APPEND command, this SHOULD be the date and time as specified in
the APPEND command description. All other cases are
implementation defined.
I don't recall seeing this problem before. If you are seeing it a lot,
and not just caused by a misconfiguration on the mail server, I suppose
it would warrant a workaround.
