--- Comment #72 from Hans-Peter Jansen <h...@urpla.net> ---
I hate to reopen old bugs, but after a long time of silence, some changes
during this year made it reappear.
I still have/need access to an old imap server (from a liquidated company) in
my local network (openSUSE 11.1, cyrus imap, self signed certificate). On my
Tumbleweed desktop (20191210), I suffer from this issue since a few weeks with
various degrees of severity, up to a complete *DOS* (kscreenlocker_greet shows
a time in the past, almost always 04:4?, but no login) of my system (all
KDE/KF5).
Since I needed to reboot my system today morning again due to this very issue,
I decided to track this down: killing the kscreenlocker* allowed me to take a
look, and guess what: it shows "Server Authentication" warnings [SAW], up to
the point of kwin crashing (no window handles, no screen switching, ...).
Here are some interesting details:
I've added the root and imap certificate in Kleopatra a while ago, where it is
shown under Trusted certificates. (All screen texts are translated from german
on the fly, bear with me).
I can easily provoke the SAW once by restarting Kmail, but restarting akonadi
will trigger the SAW once *every* *30* *seconds*. Looks, like something
triggers an akonadi restart early in the morning, but that's not the point.
Recreating .config/ksslcertificatemanager reveals another funny detail: the
format changed over time, now it looks similar to:
[95a0e3fca10d38c8420639952ad508c1]
imap.local.domain=ExpireUTC 3019-12-12T13:33:39,SelfSignedCertificateInChain
and every time, I confirm to persist the certificate, the ExpireUTC value
changes.
So here's a summary:
* kwin should never crash if too many dialogs are shown
* the SAW should never shown more than once
* kio doesn't associate accepted certificates correctly
