Bug 496338

Application: kioworker (6.8.0)

ApplicationNotResponding [ANR]: false
Qt Version: 6.8.0
Frameworks Version: 6.8.0
Operating System: Linux 6.11.7-300.fc41.x86_64 x86_64
Windowing System: Wayland
Distribution: "Fedora Linux 41 (KDE Plasma)"
DrKonqi: 6.2.3 [CoredumpBackend]

-- Information about the crash:
everytime i try to download files from a application in the local filesystem, i get the crash error for kioworker. 
The action itself is done succesfully, but the repeated crash messages are quite annoying in the workflof.

The crash can be reproduced sometimes.

-- Backtrace:
Application: kioworker (kioworker), signal: Segmentation fault
Content of s_kcrashErrorMessage: std::unique_ptr<char []> = {get() = <optimized out>}
