Bug 478319

Application: xdg-desktop-portal-kde (5.27.9)
 (Compiled from sources)
Qt Version: 5.15.11
Frameworks Version: 5.112.0
Operating System: Linux 6.1.60-gentoo-dist x86_64
Windowing System: X11
Distribution: "Gentoo Linux"
DrKonqi: 5.27.9 [KCrashBackend]

-- Information about the crash:
While setting Firefox as the default program (between it and Brave) to open HTML files, the crash report appeared. The link I wanted to open was on Zotero and in the end was succesfully opened on Firefox, which was not set as default.

The crash can be reproduced every time.

-- Backtrace:
Application: Portal (xdg-desktop-portal-kde), signal: Aborted
