Screenshot of error

STEPS TO REPRODUCE
1. Recieve email from a IMAP server (happened from multiple IMAP server)

OBSERVED RESULT
When the `message list` `aggression` is set as `activity by date, threaded`,
sometimes a random email will be shown as some -4000 year as attached picture,
and they will be shown as (No Subject), while opening them shows subject.
Restart Kmail usually solves the issue.
[Why I mark it as critical]
It seems that Kmail's wrong behavior will effect the IMAP server. Emails that
are correctly shown on my phone will become missing (because it becomes some
email from 6000 years ago and not get synced) when I open the Kmail and trigger
the bug. This means that I have to turn off my desktop before I leave home
otherwise I will lost access to random email until I get back home.

EXPECTED RESULT
Show email in correct email.
