Crash with OfflineIMAP 6.3.4-rc2

[Vladimir Marek]

Hi,

I just noticed that offlineimap has a new home (thanks!) and decided to
give it a go. I started fresh, wiping out my local storage. The mail
started to sync happily, but at one point crashed:

========================================================================

I'm not sure if that report can be useful in any way ... While the folder
'bugster' was being synchronized (messages were being downloaded to
local storage), at the same time I was working with folder 'bugster' in
mutt, marking some messages as read (not New).

I'm not sure if I can reproduce this ...

Thank you
