Autorestarted immediately after a crash: no, this won't happen.
But yes, dbus services are started automatically when someone makes a call to 
them. Unfortunately this won't be the case with kglobalacceld. It's watching 
for X11 events to wait for a global shortcut to be pressed. So if it crashes, 
it won't be watching anymore, and nothing will happen when you press Alt+F2 or 
any other global shortcut ... until some application or KCM makes a dbus call 
to change the globalaccel configuration, which will *then* restart the 
service...
