So when you make this call:
>>        g_signal_connect (G_OBJECT (button), "clicked",
>>                          G_CALLBACK (redraw), drawing_area);

does `drawing_area' point to a GtkWidget
(that is already created at this point) ?

Maybe an isolated piece of code that reproduces this could be of help ?

Cheers,
