New crash information added by DrKonqi

akonadiserver (5.7.3) using Qt 5.9.4

- What I was doing when the application crashed:

I wasn't interacting with akonadi at all when it crashed. It might have been
fetching mail in the background. Kontact was open.

I never had this problem until I few days ago, but now there are two crashes. I
wonder if this is a coincidence or a recent change increased the chance of this
crash occurring. The last system (openSUSE Leap 15) update on 2018-09-12
installed the following packages:

While there are several KDE packages in that list, I don't think akonadiserver
would depends on the listed packages.
