Comment 4 for bug 1270894

I've written some code that exposes a reordered signal to Ristretto when the list is reordered. I've fixed some segfault-causing issue in the reordering handler. I still have some issues: the reordering goes wild!

In particular:
- the order when the app is launched is exactly the contrary to the order when
- it seems to me the order goes wild at some point... I'm suspecting the way I write the ordering in the image list!
