In 12.04 on one of my machine, I have no cropping options on the Background Settings dialog box.

Specifically, I should see a listbox with Tile, Zoom, Fill, Span, etc. as described on this page : http://askubuntu.com/questions/22681...opping-options

Yet, this listbox is completly absent from the dialog box, which is very strange.

Any suggestion on how to get it back?
