Re: [Vala] question Gtk 3 + gstreamer 1.0

[Luca Bruno <lethalman88 gmail com>]

Gstreamer fires signals in a different thread than the gui mainloop. Use
something like
Idle.add (() => { this.image_button.set_from_stock(
                Gtk.Stock.MEDIA_PLAY, Gtk.IconSize.BUTTON);
  return false; });
to run your code in the gui mainloop.
