switching wallpaper cause momentary freeze

[Vincent Tschanz]

Binary package hint: gnome-control-center

Ubuntu 9.10

What is expected:
Window let me choose quickly various wallpaper with automatic preview when I click a thumbnail.

What does happen:
On certain wallpaper (randomly) Xorg freeze for 5-10 seonds.

Xorg process eat 100% of CPU, I can move the mouse but I'm not able to just move any window.

How to reproduce:
1. Right-click Desktop and choose "change Wallpaper" (or something like that I'm using a localised version of Ubuntu)
2. Click on a diffrent wallpaper proposed by default.
3. repeat step 2 until Xorg freeze (happen between 1 or 8 selected wallpaper for me)

gnome-appearance-properties won't be responsible for making Xorg freeze. Have you got an example wallpaper which triggers this? I can't reproduce this behaviour at all

This is not happening with a specific picture.
I have a very fresh install here, no added repos. So no more wallpaper than the few shipped with Ubunutu.
All I have to do is to click randomly on a thumbnail, then after 4-8 try I have a freeze.

I have a dual-screen setup with Xinerama and I use the Nvidia restricte Driver privided by Ubuntu.
