[kde-linux] Failed to change wallpapers in kdesktop

[Willie Sun]

Hi, all

I installed the KDE 3.5 Beta 2 from source under debian testing serveral days ago, and I tried to change the wallpaper for kdesktop, strange
things happened. kdesktop does not accept every image to be shown on the desktop, I even used command line

dcop kdesktop ......

to change the wallpaper but no luck. For the default installation, for instance, wallpapers All-Good-People and Floating-Leaves did not show, but 
KDE34 did. Here is the outputs in console while I tried to change the wallpaper via command lines.

#===== ALL-Good-People : Failed -------#
$ dcop kdesktop KBackgroundIface setWallpaper /usr/share/wallpapers/All-Good-People-1.jpg 1
kdesktop: [int KVirtualBGRenderer::hash()]  fp="bm:0;en:1ca:4278202498;wm:1;wp:/usr/share/wallpapers/All-Good-People-1.jpg:1131193001;blm:0;01" h=247819777

#===== Floating-Leaves : Failed -------#
$dcop kdesktop KBackgroundIface setWallpaper /usr/share/wallpapers/floating-leaves.jpg 1
kdesktop: [int KVirtualBGRenderer::hash()]  fp="bm:0;en:1ca:4278202498;wm:1;wp:/usr/share/wallpapers/floating-leaves.jpg:1131193001;blm:0;01" h=155051633

#===== KDE3.4 : Succeed -------#
$dcop kdesktop KBackgroundIface setWallpaper /usr/share/wallpapers/KDE34.png 1
