Core dump that doesn't appear to cause issues

[raj-magesh]

I was going through my journal logs and noticed that dunst seems to coredump frequently, perhaps every time I receive a notification. It doesn't seem to cause any issues: I still receive further notifications, but I thought it'd be useful to post the output of coredumpctl info in case you'd like to fix whatever's causing it:

I'm on NixOS running niri (a Wayland compositor). Let me know if you need any more details!

Hello, I'm not familiar with nix, what is dunst-wrapped supposed to be?

[raj-magesh]

It's apparently supposed to be dunst, except with certain environment variables set.

Here's where Nix packages dunst: https://github.com/NixOS/nixpkgs/blob/master/pkgs/by-name/du/dunst/package.nix#L89-L106

As far as I can tell, it seems pretty vanilla.

[bynect]

this happens only in wayland mode? could you try Xwayland mode?
this is not supposed to happen. we had an issue where early loading of dunst (before the DE was ready) caused it to crash.
but here the problem seems to be when communicating with wayland

I'm not sure it's related, but I'm also having some core-dump logs that don't prevent dunst from running normally later:

EDIT: It might in fact be related to #1466 , which is not included in the latest release yet I believe

just in case could you upload the logs of when this happens?

[bonswouar]

If they're all in journalctl, here is the logs I've found:

Jul 14 13:56:27 fedora systemd[1801]: Starting dunst.service - Dunst notification daemon...
Jul 14 13:56:27 fedora dunst[2254]: WARNING: Cannot open X11 display.

Then core dump, and repeated 5 times during boot apparently

EDIT: And I'm also on wayland (sway)

[bynect]

okay this is the problem of #1466 👍🏻

[bynect]

@raj-magesh could you try if this happens with the latest version?
