Bug 2370334

I am using gnome-connections to connect to a server that offers an RDP service. Both the client and server run Fedora 42. I loosely followed Vladislav Grigoryev's instructions at https://discourse.gnome.org/t/headless-remote-desktop-setup-process/20411/2 to configure the server.

The server is running gdm-48.0-3.fc42.x86_64.

Watching the system logs seems to indicate GDM is causing a segmentation fault. Here is one such log:

Process 8156 (gdm) of user 0 dumped core.
