New crash information added by DrKonqi

akonadiserver (5.14.2 (20.04.2)) using Qt 5.12.7

- What I was doing when the application crashed:

This happened twice this morning:

1. I had just booted the machine and closed two windows (from a saved session)
when I was informed that Akonadi server had crashed. I was busy with
time-sensitive operations so could not report it then but I told it to restart
the app. Things continued fine, until I noticed later that I could no longer
access teh system menu (neither mouse to teh bottom of the screen nor pressing
the Meta key). until then I had been able to, so something died some time after
I successfully used the system menu.

I did have a look at the journal and there seemed to be some unusual Qt errors
(versus the usual noise pretty much every time I change window focus). I cannot
show the entries in question because (as I just discovered) the journal default
is not to save its logs. Wish I could be mroe helpful here.

2. When I got home and started up, I was informed just after logging in that
the Akonadi server had died yet again. Since I had time, I am submitting this,
as I really need to be able to use my system: at the moment I cannot get to the
system menu. Keyboard shortcuts such as changing desktops or starting Konsole
windows thankfully work, but it's a real problem to work properly.

I really hope this will get sorted out quickly, as I need to use my laptop.
