background picture not cached

[Sandra Farnedi]

gnome-settings-daemon:
  Installed: 3.4.0-0ubuntu2

I use a picture located in my destop directory to set my screen background. If I remove the picture from the desktop itself, I have no background at next reboot.
N.B. I did the same in ubuntu 11.10 environment and my background is kept on also if I remove the picture.

Great, this is reproducible on installed system too.
This mean that casper isn't the responsible of this issue, what do you think about ?

I confirm the issue

The background picture is not saved into wallpapers pictures folder.

[Fabio Marconi (fabiomarconi)]

Ok, it is /usr/share/backgrounds
To change the background we usually use System Settings - Appearance and in this way everythings works well, but we can also right-click on an image and select 'Use as background' (or something similar), in this case nautilus kick gnome-settings-daemon that copy the directory of the image and paste it in the background code but forget to copy the image into /usr/share/background too and to update the background pasted dir with the new generated /usr/share/background/copied+image.
Under this optic we cannot assign the bug to gnome-control-center that usually manage the settings for the background, but we have to blame gnome-settings-daemon.

The chosen picture background is saved in .cache/wallpaper directory but, at reboot time, the system looks for wallpapers in ~username/pictures folder and obviously doesn't find it out.

Thank you for your bug report, that seems to not be a bug, the fact that g-s-d was copying local images before was a bug and creating issues (the image infos would look weird in the capplet, unity-greeter was not able to pick it because the image was made private without reason, etc) ... what is the usecase for that? if you use an image just put it somewhere and don't delete it while relying on "magic" to keep it for you, like you wouldn't delete files you are using an expect your work editor to still reload them by magic from its backup files (or only to avoid incident, not as a standard workflow)...

[Sandra Farnedi (sandra-farnedi-d)]

Infact, if I do not delete the original picture the screen background is correctly kept, so I think we can consider the bug invalid.
