Bug 480401

Application: gwenview (23.08.4)

Qt Version: 5.15.12
Frameworks Version: 5.114.0
Operating System: Linux 6.7.1-zen1-1-zen x86_64
Windowing System: X11
Distribution: "Arch Linux"
DrKonqi: 5.27.10 [KCrashBackend]

-- Information about the crash:
Images were pretty standard JPEG images, no insane resolution. On a Btrfs RAID5 array connected over USB. There was high load on the volume when the issue occured, and I could not reproduce the issue a couple minutes later.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Gwenview (gwenview), signal: Segmentation fault
Content of s_kcrashErrorMessage: std::unique_ptr<char []> = {get() = 0x0}
