Ok, it's not Cairo Dock itself. It must be something that Cairo Dock or other packages do when starting up. Some querying or system call, maybe a timing issue?
Set Cairo Dock to start 20 seconds after login, logged out, logged back in - problem solved for me! The buttons work. Removed bash sleep command, logged out, logged in again - buttons don't work no more. Maybe some other package causes this problem for everyone else.
