mail retrieval from icloud imap server broken in evolution

[gurfle]

Running Evolution 3.22.6 in Debian 9.2
EDIT: Upgrade to latest stretch update (Debian 9.13) does not fix the problem.

A few days ago I started getting this error in evolution when trying to retrieve email from my icloud imap server:

Code: Select all

Failed to open folder.
The reported error was "Error fetching folders: Parse Error (took 0 ms)".

So I am unable to see the imap inbox of my icloud email account in evolution. Nothing seems amiss when I log into icloud through a browser.

Here are the evolution imap settings (that have worked for years until this problem occurred a few days ago (when nothing changed on my side):

Server: imap.mail.me.com
Port: 993
Username: gurfle@icloud.com
Encryption Method: TLS on a dedicated port
Authentication: Password
