[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.

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/

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

I can also confirm. This issue triggers when dragging a file into VLC, exactly when my mouse pointer is about to cross the window boundary. Dragging into Firefox works fine.

Gnome on Wayland, Intel onboard graphics, older kernel (due to unresolved kernel panics when connecting my display):

6.15.9-arch1-1 #1 SMP PREEMPT_DYNAMIC Sat, 02 Aug 2025 01:20:06 +0000 x86_64 GNU/Linux
mutter, gnome-shell, gdm: 49.1-1
