Description Patrick Silva 2023-06-27 15:16:35 UTC 
Application: isoimagewriter (1.0.0)

Qt Version: 5.15.10
Frameworks Version: 5.107.0
Operating System: Linux 6.3.9-arch1-1 x86_64
Windowing System: Wayland
Distribution: "Arch Linux"
DrKonqi: 5.27.6 [KCrashBackend]

-- Information about the crash:
I tried to create a bootable flash drive with neon-user-20230622-0716.iso file,
I chose the .ISO file, went to the next step and then the app crashed.

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: ISO Image Writer (isoimagewriter), signal: Segmentation fault
