Could this be fixed in Ubuntu with a post-install script? One would expect thumbnails in nautilus to simply work. Most people won't search the help pages and then dig into the configs and will be frustrated.

This used to work in previous Ubuntu versions, so it is a regression.

Having small thumbnails is better than having no thumbnails. To attract
a wider audience Ubuntu must have a better out-of-the box experience.
