Hello arch-general!

I have a laptop running the latest KDE / Plasma, but I use gnome-terminal as my terminal app. Recently I noticed that when I launch gnome-terminal from the KDE start menu, it takes an incredibly long time to launch (maybe 20+ seconds) and when it does launch, I just get a flashing prompt with no actual shell. If I launch a second gnome-terminal after that, *that* gnome-terminal seems fine. I get a normal working shell. If I launch xterm then the xterm is fine.

Running "journalctl -f" while I launch the initial gnome-terminal instance shows:

Googling that core dump led me to:

https://bbs.archlinux.org/viewtopic.php?id=224787

...which led me to:

https://github.com/flatpak/xdg-desktop-portal-gtk/issues/72

...which sounds a bit like what I'm seeing, at least the slowness part. However, I use SDDM, so I can't put the recommended dbus-update-activation-environment in any .xinitrc file (which is only run when you do startx as far as I know).

So, two questions:

(1) Where would I put this command so that it's run by SDDM on login?

(2) Is there a bug here where some script in /etc somewhere should be doing this? I poked around thinking maybe there was a .pacnew for some Xorg / SDDM related file that might have this, but I didn't see anything. Mostly just wondering if I should file a bug.
