[Evolution] Preview pane not updated after expunging

[Svante Signell <svante signell telia com>]

As the title says, efter expunging a folder, where deleted mails are
marked as deleted, the preview pane is not updated. The removed mails
are still visible but of course not accessible, since they are already
removed. Visiting another folder and back the mails marked for removal
have disappeared. Additionally, mails not filtered by rules in the inbox
(they should be automatically), hitting C-y does not mark the mail as
deleted, this will only be visible when moving to next mail...

Folder is an mbox area in /var/mail. Evo version 2.6.26.1.1-1 from
Debian unstable.

Thanks for any help.
