Updated title to no longer be Edubuntu specific.
For Edubuntu I just uploaded a new edubuntu-artwork including the "touch" hack I mentioned before. That should workaround the issue.
I'd suggest doing the same in ubuntu-wallpapers unless we know for sure we'll have another (cleaner ?) way of updating the cache on upgrade.
