Description Roke Julian Lockhart Beedell 2025-07-27 18:26:40 UTC 
Application: gwenview (25.04.3)

ApplicationNotResponding [ANR]: false
Qt Version: 6.9.1
Frameworks Version: 6.16.0
Operating System: Linux 6.15.7-200.fc42.x86_64 x86_64
Windowing System: Wayland
Distribution: "Fedora Linux 42 (KDE Plasma Desktop Edition)"
DrKonqi: 6.4.3 [CoredumpBackend]

-- Information about the crash:
1. I downloaded https://commons.wikimedia.org/w/index.php?title=Category:Large_images&oldid=1056636490#/media/File:%22_Shot_From_The_Sky%22_Army_Show_1945_Oak_Ridge_(24971013612).jpg.

2. I invoked the file in Gwenview.

3. I ran `truncate -s 100000MB "/home/RokeJulianLockhart/Downloads/__Shot_From_The_Sky__Army_Show_1945_Oak_Ridge_(24971013612).jpg"`.

4. Gwenview attempted to reload the file, but crashed.

Thereafter, attempting to invoke the file crashes Gwenview.

The crash can be reproduced every time.

Comment 4 Roke Julian Lockhart Beedell 2025-07-27 18:38:08 UTC 
Managed to reproduce it in Okular, too, at https://bugs.kde.org/show_bug.cgi?id=507550#c0 (although not in ShowFoto, KSnip, or Krita).
