I've found a potential workaround to this issue...

1) Add "feh" package to the live installation.
2) Remove lines 400-403 from

To test...
1) Boot live image.
2) Switch to TTY1
3) Comment out lines 400-403 in the above file.
4) Install the "feh" package.
5) Stop processes: sudo stop lightdm ; sudo stop ubiquity ; sudo pkill -9 X
6) Start ubiquity: sudo start ubiquity

Ubiquity now displays the background.

It's a usability issue that doesn't limit the functionality of a core package.

The core problem is that xfce4settings daemon, whilst spawned by ubiquity-dm it end up defunct. it should be running properly and thus displaying background during ubiquity-dm session. this is a regression in the xfce4settings or it's looking for something that is missing in the environment.
