Bug 423729

Application: akonadiserver (5.14.2 (20.04.2))

Qt Version: 5.14.2
Frameworks Version: 5.71.0
Operating System: Linux 4.15.0-108-generic x86_64
Windowing system: X11
Distribution: KDE neon User Edition 5.19

-- Information about the crash:
- What I was doing when the application crashed:
I had added a few new contacts via my web browser, and added them to a newly created label. After that I wanted to write an email to these newly created contacts from kontact, so I opened kontact, switched to the addressbook and refreshed the according google account.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Akonadi Server (akonadiserver), signal: Segmentation fault
