Windowing System: Wayland
Drkonqi Version: 5.21.80

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

Had a pdf file open in Okular, close it.

No need to have a file open to trigger the crash though, just open and close
okular to trigger the crash.

The crash can be reproduced every time.

-- Backtrace:
Application: Okular (okular), signal: Segmentation fault
