Bug 455093

Application: plasma-discover (5.24.4)

Qt Version: 5.15.2
Frameworks Version: 5.90.0
Operating System: Linux 5.14.21-150400.22-default x86_64
Windowing System: X11
Distribution: "openSUSE Leap 15.4"
DrKonqi: 5.24.4 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
I just downloaded the flatpak file from the official Telegram website, asked Discover to install it (via flatpak ofc) and there it was. It is just dead now. All this on a fresh system install.

The reporter is unsure if this crash is reproducible.

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