I have a large IMAP box running on a remote dovecot server, with several GB of messages in hundreds of folders. Evolution is set up with an imapx sync against this mailbox.

When going offline (e.g., changing wireless networks with the NetworkManager), Evolution sometimes gets into a state where it invalidates all cached folders, forcing a redownload of the entire mailbox.
This has happened several times over the last months, but for a few days now, it happens several times per day. It makes the mailer completely unusable.
When I change networks during the resync, the bug is pretty much reproducible.


I will attach redacted relevant portions of the syslog.
