Trying to set a desktop background in Gnome-Flashback

[Christian Ovsenik]

I am trying to set a desktop background in gnome-flashback. The background remains a kind of plum color and this error is displayed in the terminal (if I run gnome-control-center from there):

christian@endor:/etc$ gnome-control-center

(gnome-control-center:4191): background-cc-panel-WARNING **: 20:54:24.409: Failed to load image: Unrecognized image file format

I tried with .png and .jpg images.

This worked in 18.10.

In gnome DE and Ubuntu DE desktop backgrounds work fine. I can set any of the images I tried as wallpapers.

This bug was fixed in the package gnome-flashback - 3.30.0-1ubuntu5

---------------
gnome-flashback (3.30.0-1ubuntu5) disco; urgency=medium

  * Make gnome-flashback-common depend on light-themes, as that package
    ships a gsettings-override file which sets gtk-theme to Ambiance.
  * Stop disabling desktop-background component (LP: #1816500).
