Description Robert Riemann 2024-05-16 08:52:19 UTC

Application: plasma-discover (6.0.4)

Qt Version: 6.7.0
Frameworks Version: 6.2.0
Operating System: Linux 6.8.9-300.fc40.x86_64 x86_64
Windowing System: Wayland
Distribution: "Fedora Linux 40.20240514.0 (Kinoite)"
DrKonqi: 6.0.4 [CoredumpBackend]

-- Information about the crash:
I am on Fedora Kinoite 40 (atomic distro) and have firefox as part of the base image. I was thinking of installing firefox also as flatpak to have h264 playback support. When I wanted to check out firefox from other (flatpak) sources, the app crashed.

The reporter is unsure if this crash is reproducible.

Comment 2 Robert Riemann 2024-05-16 08:56:22 UTC

I can reproduce this bug. I search for "firefox", I click on the first search result, I switch source from "fedora" to "flathub" and the app crashes after a delay of 2 seconds.
