New submission from anonymous:

Quite often (~50% of trials) an email gets sent but right after that sup tries to 
save it in the INBOX.Sent folder and crashes. Sometimes it works though. Here's 
the stripped config for that folder:

sources.yaml:
- !masanjin.net,2006-10-01/Redwood/IMAP
  uri: imaps://mail.example.com/INBOX.Sent
  ...
  usual: false
  archived: false
  id: 2
  labels: []

config.yaml:
:sent_source: imaps://mail.idiles.com/INBOX.Sent

Thank you!
