Bug 466845

Application: kdialog (22.12.2)

Qt Version: 5.15.8
Frameworks Version: 5.103.0
Operating System: Linux 6.2.0-63.fc38.x86_64 x86_64
Windowing System: Wayland
Distribution: Fedora Linux 38 (KDE Plasma Prerelease)
DrKonqi: 5.27.2 [KCrashBackend]

-- Information about the crash:
This was a file open dialog brought up by Chrome to select an avatar. I went to a directory, enabled previews, clicked on a few images, then clicked on the parent directory, and kdialog crashed.  (I might have missed some step).

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: KDialog (kdialog), signal: Segmentation fault
