[BUG] Caja Desktop is started before Mate-settings-daemon is ready

[ghostplant]

Expected behaviour

caja --desktop should start after Mate-settings-daemon is ready.

Actual behaviour

caja --desktop is sometimes before Mate-settings-daemon is ready, making caja desktop theme is totally difference with theme planned by Mate-settings-daemon.

Steps to reproduce the behaviour

kill both caja and mate-settings-daemon, firstly run caja desktop and then run mate-settings-daemon.

MATE general version

MATE in Ubuntu 22.04

---

I tried to postpone starting caja until pgrep -f mate-settings-daemon is satisfied, but it still doesn't work because mate-settings-daemon needs some seconds to become fully prepared. I want to know what is a accurate signal that tells me mate-settings-daemon is fully ready and it would be okay to start up caja desktop.
