Here's the leak: on each round, you order an animation iterator with
gdk_pixbuf_animation_get_iter(...) just to throw it away without
unref()ing it.
The way to avoid this leak might be:
| GdkPixbufAnimationIter *iter =
gdk_pixbuf_animation_get_iter(waitImageAnimated, NULL);
| while(...) {
| ...
| gtk_image_set_from_pixbuf(gdk_pixbuf_animation_iter_get_pixbuf(iter));
| }
| g_object_unref(G_OBJECT(iter));
As I understand the doc, you don't have to unref the pixbufs you get
from the iterator (but the iterator itself!). Plus you don't have to
dreate a new iterator on each round of your loop (I guess it would start
at the first image of the animation each time anyway).
But I don't understand why you try to do it all yourself. There is an
gtk_image_set_from_animation() which should just work for you (plus, if
you want to step all by yourself through the anim frames, maybe you
should do it in a timer or idle func, instead of doing the gtk loop by
hand and getting into hot water about that ;)
