KDE and wallpaper change

[Marq]

Hi!

I'm using Qt 4.5.3 | KDE: 4.3.2, and i've noticed a problem with destkop wallpaper changing via right button click on desktop -> desktop settings and there i choose an image for wallpaper. When i try to choose a wallpaper from list, there is no wallpapers thumbnails. Furthermore after click on directory button to choose custom wallpaper, plasma just hangs, when i get to console by alt+ctrl+f1, there is message like that:

KdirWatch: "/usr/share/wallpapers/xxxx/" is a directory! use addDir!

And after 2-3 minutes file explorer shows up, but with no folder contents (even if i click on Home Directory button on the left side there's only progress bar with 0% permanently). The only way to change wallpaper is change desktop background type to slideshow and copy wallpaper to added directory. Any ideas?
