New crash information added by DrKonqi

kontact (5.14.2 (20.04.2)) using Qt 5.15.0

- What I was doing when the application crashed:
reading emails. More precisely, a Whatsapp message had also popped up (via firefox)

- Custom settings of the application:

The backtrace isn't complete as there are missing debug symbols, but my guess would be this is a duplicate of bug 401865.

I have worked around this by deleting the whole database, and setting up the kmail from scratch. Interestingly, the mail database comprised around 30Gb of data, which is insane.
Either it was the size of the data base or some incompatibility due to Arch's rolling release model. 
Now everything is working again and I don't experience crashes anymore. 
Even gmail stuff works again.  
This might not be the desired solution, but maybe it helps somebody with the same problem.
