Application: korgac (5.1.3)

Qt Version: 5.5.1
Frameworks Version: 5.23.0
Operating System: Linux 4.4.0-36-generic x86_64
Distribution: Ubuntu 16.04.1 LTS

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

Kontact was running after fresh booting and log into Kubuntu.
I stopped and started akonadi by "akonadictl stop" and "akonadictl start".
KOrganizer Reminder Daemon crashes.

This happened several times after first login. However, Iacanot repeat the crash directly afterwards.

BTW: There is a  reason for manually stopping and strarting akonadi: My Kmail filters won't work. Restarting akonadi is my work around to make them work again. This happens several times a day.

The crash can be reproduced sometimes.

-- Backtrace:
Application: KOrganizer-Erinnerungsmodul (korgac), signal: Segmentation fault
