[GNOME 49 / Mutter 17] gnome-shell Segfault During Drag & Drop

Steps to reproduce:

1. System: Arch Linux (rolling)

2. Session: GNOME on Wayland, NVIDIA driver

3. Action: Drag a file from Files (nautilus) to another application → GDM / gnome-shell crashes and restarts.

Observed:

gnome-shell segfaults and GDM restarts.

Relevant logs:

Oct 16 09:19:55.670606 dellarch kernel: gnome-shell[1234392]: segfault at 0 ip 00007f03f49b0e6b sp 00007ffee5e1c580 error 4 in libmutter-17.so.0.0.0[1b0e6b,7f03f483c000+1da000] likely on CPU 8 (core 16, socket 0)

(systemd-coredump recorded the core)

Computed offset in libmutter:

IP: 0x7f03f49b0e6b
lib base: 0x7f03f483c000
offset: 0x174e6b

What I have attached:

• `journalctl` around crash time (gnome-shell and gdm)

• `coredumpctl info 1234392` output

• full `coredumpctl gdb` backtrace (if needed)

• `uname -a` and `pacman -Qi mutter gnome-shell gdm nvidia`

Additional helpful notes:

* I can provide the coredump if maintainers want it.
* I can also try with/without Wayland (GNOME on Xorg) to confirm whether this is Wayland-specific.

Question:
Has anyone else experienced similar gnome-shell crashes after the recent October updates (GNOME 49.1 + NVIDIA + Wayland)?
If yes, please confirm whether it happens during drag-and-drop from Files to other apps.

Re: [GNOME 49 / Mutter 17] gnome-shell Segfault During Drag & Drop

I can confirm, I'm seeing identical behavior when dragging and dropping files from Nautilus into the steam client.  Gnome-shell segfaults and drops me back to GDM.

Relevant journal looks about like yours, I am also using a wayland session.  I am on the same gnome package versions as you (mutter 49.1-2, etc.), with the exception that I use amdgpu instead of nvidia.   I noticed this behavior for the first time today, so I agree that it's likely linked to recent mutter and/or gnome-shell updates

Thanks for confirming!
Really appreciate you checking. it’s good to know this isn’t NVIDIA-specific since you’re seeing the same segfault on AMDGPU with identical mutter/gnome-shell versions.

Re: [GNOME 49 / Mutter 17] gnome-shell Segfault During Drag & Drop

What I have attached:
    `journalctl` around crash time (gnome-shell and gdm)
    `coredumpctl info 1234392` output
    full `coredumpctl gdb` backtrace (if needed)

Where? The coredump (ideally w/ https://wiki.archlinux.org/title/Debuginfod ) will allow to check whether this has already been recorded at https://gitlab.gnome.org/GNOME/
