Thread 18 detected memory corruption, could be caused previously by any other thread. Probably only a valgrind log could help to isolate the cause of the issue. If this is reproducible, please try to generate a valgrind log.

Comment 2 Till Schäfer 2017-12-19 20:07:27 UTC 
This is not reproducible... I have only seen it once. 

Should we close the bug then?

New crash information added by DrKonqi

akonadiserver (5.7.3) using Qt 5.9.6

- What I was doing when the application crashed:

I didn't actively do anything: Kontact was running, but minimized in the background and I haven't interacted with it for several minutes.

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.
