Application: configure-printer (0.5.0)

Qt Version: 5.11.2
Frameworks Version: 5.52.0
Operating System: Linux 4.18.0-3-amd64 x86_64
Distribution: Debian GNU/Linux buster/sid

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

Closed the printer queue window after viewing the list of queued printer jobs, no other interaction took place. Just opening (through the plasmoid) and closing the window is enough to reproduce this crash.

- Custom settings of the application:

Running under Wayland.

The crash can be reproduced every time.

-- Backtrace:
