Bug 463453

SUMMARY
I have noticed that today the wallpaper is meant to change, but it only changed for one display instead of all.
Global Theme: "Breath Dark"
Wallpaper normal: "Bamboo at Night"
Wallpaper event: "North" (images_dark)


STEPS TO REPRODUCE
1. have multiple displays
2. have the theme setup described in "summary"
3. ensure no event is currently set for the system time
4. reboot into a time where a event is
5. observe the wallpaper not being updated for all displays

OBSERVED RESULT
Wallpaper only changed for one display

EXPECTED RESULT
Wallpaper should update for all displays

ADDITIONAL INFORMATION
i was not sure under which component to file this under.

i have also noticed that when going to Wallpaper settings from the one display that changed, it does not highlight any wallpaper as used.
i dont know if this intentional, but i have also noticed that the currently used wallpaper is duplicated in the Wallpaper selection, once showing with the name and author and once at the beginning only showing the resolution, but both show the same image and link to the same place.

Note: in the screenshot the middle display is the primary display, in case that matters.
Note: i am listing this as "event" because the wallpaper suddenly changed, without me setting it or (from what i can tell) updating a theme package and it also happened in a time frame where it is reasonable to think it is a event.
