SegFault when using setproperty! after getproperty

[rodrigolece]

I want to change the label of a button after I press it. I also need the label it had before, in order to know how to change it. I can pefectly use setproperty! and getproperty separately, but not one after the other:

using Gtk.ShortNames

b = @Button("B")
win = @Window(b, "SegFault")
showall(win

function button_clicked_callback(widget)
    println(getproperty(widget, :label, AbstractString))
    setproperty!(widget, :label, "ON")
end

signal_connect(button_clicked_callback, b, :clicked)

I get a SegFault both in the REPL and running the above code as script (modified accordingly). I am running Mac OS 10.9.5, Julia 0.4.2 and Gtk 0.9.2.
