Composition problem with Geforce 7025

I am encountering a major bug with NVidia 304.131 driver on Arch. Using Gnome, as soon as I open a window, the gnome-shell crashes, and some problems related to NVidia drivers can be found on the logs. I already talked about the problem in the Arch Forum at, and I also made different tries. I suspect that the problem is composite-related because I am able to run XFCE4, which does not use composite, flawlessly.
Oh, I started having this issues on two identical PCs (therefore it is not an hardware related problem) after an upgrade of Gnome (probably some changes on compositing systems).
