Summary: xdg-desktop-portal crashes after update to Plasma 6.1
when screen casting

SUMMARY
I updated to Plasma 6.1 the day before yesterday and since then
xdg-desktop-portal crashes when I try to share my screen. I (have to) use Teams
and I use the teams-for-linux Flatpak (cf.
https://flathub.org/de/apps/com.github.IsmaelMartinez.teams_for_linux). I use
screen sharing almost daily so I am sure it worked earlier this week.
The odd thing is that neither flatpak nor xdg-desktop-portal nor libpipewire
was updated according to apt's history.log (attached). My guess is that somehow
xdg-desktop-portal-kde (which was updated) cases this (I don't fully understand
how these components work together).
I found some older bug from 2023 which affected Ubuntu 22.04 which sound
similar and were caused by version incompatibilities in pipewire
(https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/2964) in the one
case and something in xdg-desktop-portal in another case
(https://github.com/flatpak/xdg-desktop-portal/issues/771). But the stack
traces look differently and those should either have been fixed or have
affected me a long time ago.
STEPS TO REPRODUCE
I can 100% reproduce this with these steps but I will try to find another
reproducer with another piece of software:
1. Install and start teams-for-linux Flatpak
2. Start a call and start screen sharing
3. The xdg-desktop-portal-kde dialog will pop up, select a screen to share and
confirm
4. The screen share button in Teams will be red for a moment (as it is when you
do screen sharing) and then go back to the normal state
5. At the same time the red screen sharing KDE notification will appear in the
tray bar and stay like that
6. Check your journal or coredumpctl or drkonqi-coredump-gui and you will see
the crash
OBSERVED RESULT
Screen sharing does not work and xdg-desktop-portal crashes
EXPECTED RESULT
Screen sharing should work and xdg-desktop-portal should not crash
