Doesn't work. There's no guarantee the user has a writable config
database at all, it's totally legitimate not to have one. Then the
value won't change and ergo no notification.

GConf is not an IPC mechanism. Use proper IDL. ;-)

I believe it's fixed in GTK 2 because the theme change notification
comes via an xsetting which is monitored by looking at PropertyNotify
on the root window or something, i.e. you don't need a realized window
in order to get the notify.

The xsetting properties will mirror a GConf key (gnome-settings-daemon
propagates from gconf to xsetting, I believe).
