I've got a trouble that I tink is directly related to this bug.

When my screen is lock (idle time or resume), I see the screensaver, enter my password, and the screensaver keeps running like a kind of animated wallpaper. I just have to kill the process to be able to use my computer normally.

I also tried to run gnome-screensaver-preferences and got a stange result :
- run gnome-screensaver-preferences
- click on a screensaver => it will run the preview it normally
- click on something else : a button, an other screensaver, or try to close the window => the preview keep running by the windows won't close.

I tried to to a backtrace of this and got this (extract) :
(no debugging symbols found)

This bug may be related to bug #338371 (or at least the trouble I got).
