Bug 453841

Application: plasma-discover (5.24.5)

Qt Version: 5.15.4
Frameworks Version: 5.94.0
Operating System: Linux 5.17.7-arch1-1 x86_64
Windowing System: X11
Distribution: "Arch Linux"
DrKonqi: 5.24.5 [KCrashBackend]

-- Information about the crash:
Steps to reproduce:
1. Open Discover
2. Select "Plasma Addons"
3. Select "Fonts"
4. Click on a font (NOT on Install, just on a font in the listing). It doesn't seem to matter which one. "OpenLogos" for example trigger the issue. As do many other ones.

Non-fonts do not trigger the issue (haven't tried every category, but at least several non-fonts work).

The crash can be reproduced every time.

Possibly relevant background info: It does not matter if the optional dependency packagekit-qt5 (described as needed "to manage packages from Arch Linux repositories") is installed or not. The crash occurs regardless. I have not tried uninstalling the two other optional dependencies (flatpak and fwupd) as I'd rather not have to set those up again.

-- Backtrace:
Application: Discover (plasma-discover), signal: Segmentation fault

NOTE: I got this backtrace manually from gdb, as drkonqi did not seem to properly load the debug symbols using debuginfod for whatever reason.

Thread 1 "plasma-discover" received signal SIGSEGV, Segmentation fault.
