Opened a bug for gsettings failure described in comment #26:
gsettings fails to set wallpaper 1490543
Gsettings fails on both the Lenovo M58p with the hashing problem Gsettings also fails on Acer 5253 laptop which does not have the hashing problem
In both pc's Settings Appearance Wallpapers Pictures folder works, but on the Lenovo may have to be repeated several times.
