Application: akonadiserver (5.7.3)

Qt Version: 5.9.5
Frameworks Version: 5.46.0
Operating System: Linux 4.15.0-23-generic x86_64
Distribution: Ubuntu 18.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
running "akonadictl fsck"
- Unusual behavior I noticed:
akonadi crashed already twice at login, but started then and worked (kmail ran and worked as expected)
On sending an email, akonadi crashed again. Restarted the server by "akonadictl start", which produced no (obvious) errors. Running "akonadictl fsck" lead to a new crash and does so hence, while "akonadictl start"  works most of the times.

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".
