On Jaunty, when the image file being used as desktop background is overwritten or changed, the whole desktop freezes for 15 seconds. The Xorg just after the freeze is shown at 99% CPU, but I can't be sure of what is happening because everything freezes.
Steps to reproduce:
1) Find the current image used:
$ gconftool-2 -g /desktop/gnome/background/picture_filename
/home/.../imgs/current_bg.png
2) Copy the file to another location
$ cp /home/.../imgs/current_bg.png /tmp/tmp.png
3) Copy the new file back to the original position
$ cp /tmp/tmp.png /home/bisho/imgs/current_bg.png
After some seconds, the desktop while freeze for about 15 secs. The mouse still moves, but the cursor doesn't change depending on the context, windows are not responsive, pannels are freezed...
I noticed this because I have a program to change background image including the earth with the proper shadow, and modify the image every 30 minutes.
This began happening after upgrading to jaunty. Previously this was working fine.

I also noticed that changing the background with:
gconftool-2 -t str -s /desktop/
Also makes desktop freeze. It may be happening on all background changes?
