appearance – can't remove wallpapers from the 'Pictures Folder' widget

[Thibaut Brandscheid]

I added some wallpapers by clicking the '+' button in the system settings appearance 'Pictures Folder' window. Then tried to remove a single wallpaper by selecting a wallpaper and clicking the '-' button → right now it's not possible to remove a wallpaper in the 'Pictures Folder' widget, the '-' button is gray (inactive).
