Comment 6 for bug 1776475

Summary: twice, bug happened when service org.gtk.vfs.Daemon is activating *after* org.a11y.atspi.Registry is activated.

Details below.

Bug just happened again on unlocking session (versus switching users).

I compared the output of journalctl.

## Around unlock time: nothing to see

Around unlock time, journalctl only shows lightdm cleanup activity. Then, only when bug happens, lightdm starts again the whole sequence :

systemd[somepid]: Starting User Manager for UID 110...
systemd-logind[749]: New session c9 of user lightdm.
systemd[somepid]: Started Session c9 of user lightdm.
...

## Around lock time: same correlation between log order and bug occurrence

Again

Indeed, bug happens when log is in this order:

at-spi-bus-launcher[25560]: dbus-daemon[25565]: Activating service name='org.a11y.atspi.Registry' requested by ':1.0' (uid=110 pid=25557 comm="/usr/sbin/lightdm-gtk-greeter " label="unconfined")
at-spi-bus-launcher[25560]: dbus-daemon[25565]: Successfully activated service 'org.a11y.atspi.Registry'
at-spi-bus-launcher[25560]: SpiRegistry daemon is running with well-known name - org.a11y.atspi.Registry
dbus-daemon[25559]: [session uid=110 pid=25559] Activating via systemd: service name='org.gtk.vfs.Daemon' unit='gvfs-daemon.service' requested by ':1.4' (uid=110 pid=25557 comm="/usr/sbin/lightdm-gtk-greeter " label="unconfined")

and things go smoothly when log is in this order:

at-spi-bus-launcher[15685]: dbus-daemon[15690]: Activating service name='org.a11y.atspi.Registry' requested by ':1.0' (uid=110 pid=15682 comm="/usr/sbin/lightdm-gtk-greeter " label="unconfined")
dbus-daemon[15684]: [session uid=110 pid=15684] Activating via systemd: service name='org.gtk.vfs.Daemon' unit='gvfs-daemon.service' requested by ':1.3' (uid=110 pid=15682 comm="/usr/sbin/lightdm-gtk-greeter " label="unconfined")
at-spi-bus-launcher[15685]: dbus-daemon[15690]: Successfully activated service 'org.a11y.atspi.Registry'
at-spi-bus-launcher[15685]: SpiRegistry daemon is running with well-known name - org.a11y.atspi.Registry

Summary: twice, bug happened when service org.gtk.vfs.Daemon is activating *after* org.a11y.atspi.Registry is activated.
