Qt Version: 6.9.1
Frameworks Version: 6.15.0

Windowing System: Wayland

-- Information about the crash:
xdg-desktop-portal-kde seems to crash on a Firefox save.

The stack trace complain about pulseaudio memfd being unavailable - not sure why xdg-desktop-kde calls this.

Another fact, is that the system has been in "Sleep", and "Resumed" once during this boot.

There have been several files of same type saved during this session, so it does not seem easily reproducable.

The reporter is unsure if this crash is reproducible.

When I say "Sleep" I mean to suspend-to-RAM btw.
