QtRuby already does, but setVisible() is the same as 'visible?', not 
'visible'. It should be this:

    STDERR.puts "focusin #{@rubid} #{self.class} #{self.parent.class} 
V:#{self.visible?}"

It prints:

focusin 4 PalgaEdit Qt::Widget V:false

I think it's seg faulted in this case because you're catching the 
method_missing() exception, and carrying on anyway. It doesn't seg fault 
after the above fix.
