Hehe erm, what do you mean by that? All programs necessarily run from RAM (on a regular PC) and a segfault is, by definition, such a program trying to access a bit of RAM it isn't allowed to. In particular, this time it's tried to access address '4' which indicates that rather than a true null-pointer dereference it's probably a dereference of an element of a null struct.
The segfault thrown from within libGL while it was being used from kwin_opengl_tes so the problem is in the desktop compositing. Have a good look over the Ubuntu forums and bugzilla and see whether you can see anyone else having the same kind of problem, otherwise it's probably a fault with the graphics card initialisation. If you can't find a software issue (like upgrading kernel, graphics driver version etc) then just try re-seating the graphics card. If that's not a go then disable opengl compositing and see whether the problem goes away.
Hope this helps :-)
