Bug 448276

Application: kget (21.4.3)

Qt Version: 5.15.2
Frameworks Version: 5.89.0
Operating System: Linux 5.15.12-200.fc35.x86_64 x86_64
Windowing System: Wayland
Distribution: Fedora Linux 35 (KDE Plasma)
DrKonqi: 5.23.4 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:

When copying a download link to Kget, or using the Firefox Kget extension, or using Falkons external download manager feature, Kget always crashes when attempting to download from Archive.org. Other websites seem to work fine. This can be reproduced easily. I was attempting to download large files, over 15GB, so maybe that has something to do with it.

- Custom settings of the application:

The crash can be reproduced every time.

-- Backtrace:
Application: KGet (kget), signal: Segmentation fault
