Ok. This is easily reproducible. I'm on it.

This is odd. The crash is in the child-focus-changed signal handler, which is getting passed an unexpectedly NULL box. The same behaviour is evidenced by the nl-places-manager, too.

The strange strange thing is that at the point the signal is being raised, child->box is a perfectly valid object. Somewhere between
g_signal_emit_by_name (actor, "child-focus-changed", &child->box);
and the on_child_focus_changed signal handler actually getting called that pointer is getting NULLed.

While I was there I noticed that the marshaller set for the child-focus-changed signal in ctk-actor.c looks wrong; it's g_ccloseru_marshal_VOID_ENUM, but the signal gets passed a ClutterActorBox *, not an enum.

@Chris:
I fixed another bug with the same behavior. Look at commit 469 in the trunk. box was first passed with the right signal, but then the signal was respawing with an empty box. Testing the pointer isn't null fix it and still enable keyboard navigation.

netbook-launcher is part of lucid Desktop and no longer supported. I'm sorry I don't have better news.
