From the START time of my users dbus-daemon I see it's started too late, somewhere between by failing evolution starts, but not after the Xfce login this morning.
I checked all dbus related recent updates, and there was nothing. lightdm wasn't updated. Only major update of Xfce 4.18.0 to 4.20.0
Which Window Manager / Desktop Environment are you using?

No idea what happens, if the service is missing after you killed the lightdm one, please try. Maybe a new user process is started then.

I am using the i3 window manager, but there are lots of xfce elements (eg.thunar file manager, mousepad and xfce terminal).

Does that mean, killing the dbus-daemon process makes always a new process being started as lightdm user?
Ok, for now it does not seem to be WM related, there are users with Xfce (me), i3 (Da51d), Mate(dumi)...
Are all of you using lightdm as Login-manager?

So you have never seen Evolution starting recently with either version of the webkit-gtk? Then it's different again on your installation, here it is working sometimes and can't say why.
So for now we have 3 (probably duplicate) tickets:Bug 886485 mail-client/evolution-3.46.2 hangs forever after printing out error message 'bwrap: Can't find source path /run/user/1000/at-spi: No such file or directory'
Bug 903543 mail-client/evolution does not start, gives "Failed to connect to socket /root/.cache/at-spi/bus_0: Permission denied"
Bug 949238 mail-client/evolution fails to start Which means, the issue is not new and existed almost 3 years ago, I haven't seen it before.
Can someone please cross-reference the tickets by See Also:, I don't have the permissions to do.

on my second PC, where i have same problem with evolution running command:
| Code: | | /usr/libexec/at-spi-bus-launcher --launch-immediately |
helps too.
When the at-spi daemon is running for my user, evolution starts fine, if it is not running (at-spi), evolution tryes to pick proccess (socket) from other user (for me is root) and fails to start with no permission error.
So i thnik the problem is with the ap-spi not running, but why? Before upgrading the system (emerge -va -1uD @world, about 600 packages), everything was working fine.
My both computers behave the same way. computers have slightly different config, but basic is the same, Lightdm / Mate / Evolution.
PS: sorry for my bad english, i hope that my messages are understandable.

Also, I am getting issues with mousepad and thunar, as shown in .xsession-errors
| Code: |
(mousepad:2519): dbind-WARNING **: 10:39:28.103: Couldn't connect to accessibility bus: Failed to connect to socket /run/user/134/at-spi/bus_0: Permission denied
(thunar:2413): dbind-WARNING **: 10:37:58.351: Couldn't connect to accessibility bus: Failed to connect to socket /run/user/134/at-spi/bus_0: Permission denied |
(Although Thunar and Mousepad both still work)

I noticed, after several working days and reboots, having webkit-gtk-2.44.4-r410 installed, evolution just starts after a reboot, having 2.46.5-r410 it fails initially.
When it fails, I only have 1 dbus-daemon.*accessibility running for lightdm: | Code: | $ ps aux |grep '[d]bus-daemon.*accessibility'
lightdm 5619 0.0 0.0 6040 3200 ? S 06:56 0:00 /usr/bin/dbus-daemon --config-file=/usr/share/defaults/at-spi2/accessibility.conf --nofork --print-address 10 --address=unix:path=/run/user/1007/at-spi/bus_0 |
It does not help to kill this.
I have more issues with the recent updates, such as the xscreensaver daemon is not running after restart. xscreensaver-settings offers to start the daemon and it does successfully. After doing so, this also started the appropriate dbus-daemon for my user and makes evolution start: | Code: | $ ps aux |grep '[d]bus-daemon.*accessibility'
mb 9580 0.0 0.0 6032 3556 ? S 07:04 0:00 /usr/bin/dbus-daemon --config-file=/usr/share/defaults/at-spi2/accessibility.conf --nofork --print-address 10 --address=unix:path=/run/user/4728/at-spi/bus_0 |

Based on https://bugs.gentoo.org/886485#c19 I wonder, if OpenRC is related to this issue, while it is not introducing the bug itself. I'm using sys-apps/openrc-0.55.1 since December 2024. I wonder, if all of you affected by the issue are also using OpenRC as Init system? That would explain why binary distros have not reported the issue yet, as they are almost all migrated to systemd. As we know it's not related to the Desktop Environment as users with Xfce, i3, Mate have already reported, though all of them Gtk-based.
Forums are missing tables so I started an ASCII table of my setup, please comment about your setups by copy and append your details to the table... | Code: | User Window Manager(WM) Desktop Environment(DE) Display Server(DS) Login Manager(LM) Init

However, everything seems to work apart from evolution.

I can confirm that switching to the slim display-manager resolves all problems...no Xsession errors and evolution works perfectly.
(Using i3wm)
Edit...but it has broken pulseaudio
Edit....likewise having no display manager and using startx also resolves the problem, but also breaks pulseaudio.

I haven't given up....but I'm struggling to understand something. The permissions on the offending socket would appear to be very permissive:
| Code: | # stat /run/user/134/at-spi/bus_0
File: /run/user/134/at-spi/bus_0
Size: 0 Blocks: 0 IO Block: 4096 socket
Device: 0,33 Inode: 7 Links: 1
Access: (0777/srwxrwxrwx) Uid: ( 134/ lightdm) Gid: ( 134/ lightdm)
Access: 2025-02-08 07:07:30.921859185 +0000
Modify: 2025-02-08 07:07:30.755192641 +0000
Change: 2025-02-08 07:07:30.755192641 +0000
Birth: 2025-02-08 07:07:30.755192641 +0000 |
If I try to connect to it as root, no problem
| Code: | # nc -U -z /run/user/134/at-spi/bus_0
# |
However, if I try to connect as an ordinary unprivileged user:
| Code: | $ nc -U -z /run/user/134/at-spi/bus_0
nc: /run/user/134/at-spi/bus_0: Permission denied |
Why is this being denied on a file with these permissions?
