Fairly well I think.

The bug is actually caused by the gdk-pixbuf library so you will find
the same problem in gThumb and GtkImageView because they all depend on
the same library. I think the problem is that the animation loader
stores each frame in memory which is not so smart.

Great, I'll post one asap then.

Maybe it's a chicken and egg problem. GtkImageView is not GNOME
blessed(TM) so no GNOME app can use it and it can't be "blessed"
because no GNOME app use it. I don't know how to get around that, but
I thought suggesting a branch in EOG would be a good start. But it is
true that the GNOME module inclusion/external dependency process is
quite tricky indeed.
