Oh, yeah... I think I get it now: it's just a race condition between the
shell and metacity:

1) we run metacity
2) we run the shell
3) metacity grabs alt-TAB
4) the shell goes idle and invokes setup_keyhandler_cb in sugar-session
5) KeyHandler tries to grab alt-TAB, but fails
5) the shell receives the "window-manager-changed" event
6) the shell tells metacity to hand off alt-tab

So it seems we could solve the issue by moving the initialization of the
KeyHandler into setup_keyhandler_cb.
