Description Emmanuele Bassi (:ebassi) 2013-06-26 21:40:46 UTC 
gtk_widget_set_opacity() unconditionally calls gtk_widget_update_alpha(), which tries to access the GdkWindow → BOOM.

I think it should be enough to move the update_alpha() under a condition check on get_realized(); once the widget is realized, there should be an emission of GtkWidget::style-updated, which in turn will call update_alpha().

fixed this in master.
