Sentry Crash Report:

Description pat_h 2020-02-22 10:50:20 UTC 
Application: akonadiserver (5.12.3)

Qt Version: 5.12.5
Frameworks Version: 5.62.0
Operating System: Linux 5.4.0-4-amd64 x86_64
Distribution: Debian GNU/Linux bullseye/sid

-- Information about the crash:
- What I was doing when the application crashed:
Login

The behavior seems to be coming from updating the system. However, as the instability already occured with an older update, it's probably not easy to tell which version mostly worked.

The crash can be reproduced every time.

-- Backtrace:
Application: Akonadi Server (akonadiserver), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
