You are correct, this needs time logging as well.

The order of changing the wallpapers in this file is this:

Fondos pantalla tios/052-1.jpg - this was the initial wallpaper
Fondos pantalla tios/5f2c22cb4a5380af7ca75622a6426917.jpg - maybe Variety tried to change to this at startup?
Fondos pantalla tios/052-1.jpg - not sure why it is reverting back, was this triggered manually by you or did Variety do this?
Fondos pantalla tios/ryanhothunk014.jpg - this is reported as a result of a "regular change", i.e. 5 minutes have passed.

By any chance do you remember which wallpaper you started with and with which one you ended up with? Are any of these changes above manual?

Also, is it possible that Variety is in fact changing the wallpaper at start, but this happens before Unity is fully initialized and shown, so you don't see the change itself, but see directly the final wallpaper? If you shutdown at one wallpaper and next time when you start you see another one, without seeing it change - this may be the case.
