Frameworks Version: 5.90.0
Operating System: Linux 5.14.21-150400.24.11-default x86_64
Windowing System: X11

DrKonqi: 5.24.4 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
Trying to install Discord from Flathub. I was successful in installing Discord through the terminal; I only had issues when opening the .flatpakref file from Flathub. After installing Discord through the terminal using the command line flatpak command, the .flatpakref file opens properly with KDE Discover. I am unable to reproduce this issue once this was performed. My system was a fresh installation of OpenSUSE Leap 15.4 before this change.

The crash can be reproduced every time.

-- Backtrace:
Application: Discover (plasma-discover), signal: Segmentation fault
