Package: offlineimap
Version: 6.0.3
Severity: normal
I know that his bug has been reported before, but I couldn't locate it.
Under certain still not completely reproducible conditions
(but which generally involve accessing the folders on the IMAP server
with additional clients, but not at the same time!).
See below for an explanation of what I believe is happening.
The exact TypeError:
---
Thread 'Copy message 1302 from .' terminated with exception:
Traceback (most recent call last):

IMAP server is Courier from stable btw.

So in order to reproduce the bug, I'd try the following:
- sync with offlineimap
- delete a message on the client (so offlineimap will call expunge later)
- create a new (!) message on the server
- mark the new message for deletion on the server
- sync with offlineimap
Since above log suggests that offlineimap tries to retrieve a message that was
deleted
during expunge, since it was already marked as "delete".
