Description

To reproduce problem:

• set up the desktop on 2 monitors (in my config, extended, next to each other)
• set background of monitor 1 to some image (dir A)
• set background of monitor 2 to an image in a directory with several images (dir B)
• set background of monitor 2 to change every 1 minute, random order

** optional: verify that settings for both monitors are saved and look correct (they do)

After 1 minute, desktop image on monitor 1 is changed to a random image from setting for monitor 2 -- and the setting for monitor 1 is now using dir B, though does not have the "change every N minutes" flag. After every minute, desktop image on monitor 1 is still changed.
