xdgh segfault when trying to screenshare with obs

[oliob]

Hi, on v1.2.3 I get a segfault when trying to screenshare:

Oct 30 22:19:41 myhost kernel: xdg-desktop-por[10798]: segfault at 90 ip 00007fe0e7d09a29 sp 00007ffe3dcfc5b0 error 4 in libpipewire-0.3.so.0.383.0[7fe0e7c93000+7e000] likely on CPU 17 (core 5, socket 0)
Oct 30 22:19:41 myhost kernel: Code: 00 44 89 c2 44 89 c9 44 8b 44 24 08 4c 8b 4c 24 10 e9 5b fa ff ff 66 66 2e 0f 1f 84 00 00 00 00 00 55 53 48 89 fd 48 83 ec 08 <48> 8b 8f 90 00 00 00 48 8b 7f 78 e8 67 3d ff ff 48 89 c3 48 85 c0

xdgh is running already with "-v" but no further info in logs.
All other xdg-desktop-portals (gnome etc are killed).
I am running hyprland and wayland on nvidia proprietary drivers.

I need a log. Logs are printed to stdout.

The log stopps right in the middle off logging without an error message
Only error befre is during start: [ERR] [pipewire] pw didn't allow for a context connection
Here the log:

well that means something's wrong with your pipewire.
