[Evolution] error when marking message as unread in IMAP INBOX

[Jens Lautenbacher <jtl schlund de>]

Hi, when trying to mark a message in my IMAP INBOX as unread, the
attached error dialog pops up when I try to switch to another folder.

I can do so with other IMAP clients without a problem.

Any help?
