Bug 397314

Application: korganizer (5.7.3)

Qt Version: 5.10.1
Frameworks Version: 5.47.0
Operating System: Linux 4.17.13 x86_64
Distribution: Debian GNU/Linux testing (buster)

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

Korganizer always segfaults on exit.

- Custom settings of the application:

I have setup a view filter that hides completed TODOs.

The crash can be reproduced every time.

-- Backtrace:
Application: KOrganizer (korganizer), signal: Segmentation fault
