Problem: Mails with attachment are duplicated hundreds of times in Sent folder

[Olaf Lessenich]

Hi,

same issue here on Debian unstable amd64. Nearly every sent mail with 
attachments gets duplicated a LOT of times and slowly fills up the IMAP 
server if unnoticed. I'm using offlineimap 6.5.5, my MUA is mutt (1.5.23) 
as well.

Nothing in my xsession-errors here, though.

Kind regards,
Olaf
