Application: korgac (5.1.3)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-18-generic x86_64
Distribution: Ubuntu 16.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
akonadictl start
- Custom settings of the application:
When I had stopped akonadi earlier, it was because I noticed it had not downloaded from gmail in 2 days, but had continued to download from other email accounts.

The crash can be reproduced every time.

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