b3f6f67c changed the loop from while() to for() in gtk_fixed_forall(),
but that's wrong since the callback can have side-effects on the list,
in case the current child gets removed. And that's the case when the
widget is destroyed.

GtkFixedChild *child;
GList *children;
- for (children = priv->children; children; children = children->next)
+ children = priv->children;
+ while (children)
{
child = children->data;
+ children = children->next;
(* callback) (child->widget, callback_data);
}
