Bug 425942

Application: elisa (20.11.70)

Qt Version: 5.15.0
Frameworks Version: 5.74.0
Operating System: Linux 5.8.0-1-default x86_64
Windowing system: Wayland
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
After updating today to current master branch, Elisa crashes after attempting to open it.
By this I mean the Elisa interface does not even show up.

The crash can be reproduced every time.

-- Backtrace:
Application: Elisa (elisa), signal: Segmentation fault
