Bug#1031770: Info received (Bug#1031770: Info received (kontact: cannot show existing messages and will not retrieve new ones))

Hello again,

I also found the applicable upstream KDE bug:

"Akonadi fails with Mariadb 10.6.3"
https://bugs.kde.org/show_bug.cgi?id=439769

Meanwhile, applying the fix suggested for Qt 5.15 in a slightly modified form 
seems to prevent the error I experienced from occurring.

With the modified libqt5sql5-mysql package installed, I have managed to start 
Kontact, view stored messages (after some messing around with akonadiconsole, 
due to earlier troubleshooting attempts), and this message will have been sent 
from Kontact.

I conclude, then, that the upstream fix needs backporting to Qt 5.11.3 for 
Debian.

Paul
